Butuan Series · Episode 5 — The Kingdom That Wasn't: Memory, Custody, and the Mazaua Question

What the Spaniards Did Not Call It

In the surviving Spanish administrative and chronicle sources of the 16th and 17th centuries — the period in which the Butuan polity moves from tributary-mission visibility into post-contact European documentation — the polity is referred to as río de Butuán (the Butuan river-region), as provincia de Butuán, or simply as Butuán. It is not referred to as reino. The Spanish administrative vocabulary of the period had a specific term for kingdom (reino), used freely for polities the Spanish recognized as such — the reino de China, the reino de Camboja, the reino de Sián. The Spanish did not extend that term to Butuan.

This matters more than it sounds. It tells us that the people who actually arrived at the Agusan delta in the 16th century, who administered the region in the 17th, who established Recollect missions there in the 1620s, and who produced the first sustained European-language documentation of the polity, did not categorize it as a kingdom. They categorized it as a river-region and as a province. The category they chose maps reasonably well onto the polity-form the suite reconstructed in Episode 4: a federation of datu-led settlements anchored on a port-node in a river delta, with a paramount whose authority was real but bounded.

The phrase that has shaped a century and a half of Filipino school textbooks, tourism literature, museum signage, and municipal-identity work — “Kingdom of Butuan” — is not what the Spanish sources called the polity. It is something else.

The Genealogy of a Phrase

The Butuan Polities Suite (cycle 63) traced the historiographic genealogy of “Kingdom of Butuan.” The findings:

16th–17th century Spanish sources. Río de Butuán, provincia de Butuán, Butuán. No reino. Not in any administrative document, not in any Recollect or Jesuit chronicle, not in the relaciones sent back to Manila or Madrid.

18th and 19th century Spanish sources. Continue the río and provincia usage. Reino de Butuán does not appear in any Spanish-period administrative or chronicle source we located.

Late 19th-century Filipino-nationalist historiography. This is where “kingdom” enters. Pardo de Tavera, Isabelo de los Reyes, José Rizal — the propagandist and ilustrado generation — begin to use reino and kingdom language for pre-Hispanic Philippine polities including Butuan. The framing is part of the broader nationalist project of demonstrating pre-Hispanic statehood, of establishing that the Philippines had political and cultural sophistication before the Spanish arrived. The motivation is real and important. The historiographic move it produced is also a move that overclaims what the underlying evidence supports.

Early 20th-century American-period scholarship. H. Otley Beyer (1917 onward), David P. Barrows (A History of the Philippines, 1905). The “kingdom” framing is adopted and amplified. Beyer’s identification of the Butuan Tara as a Hindu/Saivite image (now superseded; see Episode 3) was part of the same kingdom-construction work — building up an image of pre-Hispanic Indianized statehood in the Mindanao south.

Mid-20th-century Filipino school textbooks. Teodoro Agoncillo, Renato Constantino. “Kingdom of Butuan” becomes a standard textbook phrase in Filipino history education. The Butuan City municipal identity construction draws on this — by the late 20th century the municipality is officially marketed as the “Cradle of Philippine Civilization” and the seat of a “Kingdom of Butuan.”

Late 20th- and early 21st-century academic scholarship. A return to chiefdom, port-of-trade, and paramountcy framing — Laura Lee Junker’s Raiding, Trading, and Feasting (1999), Kenneth Hall’s A History of Early Southeast Asia (2011) — moves the academic register away from “kingdom.” Filipino-language academic work, including Mariano Henson’s Butuan-focused monographs and Ateneo-published historical studies, takes a more nuanced framing. But the popular and municipal usage persists, largely independent of the academic correction.

The “Kingdom of Butuan” is, on this genealogy, a 19th-century-and-later historiographic construction. It was built by Filipino nationalist historians out of a real and important political project — but it carries assumptions (territorial sovereignty, dynastic continuity, fixed capital) that the evidence base does not support and that the suite has explicitly found absent or Unknown.

Why the Phrase Persists

The honest reading of the phrase’s persistence has to take the artifact-dispersal context seriously.

The objects that would materially anchor the Butuan polity’s continuity are not in Butuan. The principal Surigao gold pieces — the upavita, the Kinnari, the kamagi chains — are in the Bangko Sentral ng Pilipinas Money Museum in Manila and at the Ayala Museum in Makati. The Vajralasya — the polity’s most spectacular surviving ritual object — is at the Field Museum of Natural History in Chicago, accession 109928, where it has been since 1922. The largest of the balangay hulls (Balangay Two and Five) are under conservation custody distributed between the National Museum in Manila and the NMP Butuan branch site museum, the latter being the only place where any of the major polity-anchoring artifacts is in the polity’s own present-day city.

This is not a critique. Each of these custody decisions has its own history and its own justifications: conservation requirements, institutional capacities, the chain of legal title, the 1922 sale by which the Vajralasya passed to the Field Museum, the 1981 looting and recovery sequence by which the Surigao Treasure reached BSP and Ayala. The custody is a fact about how the polity has come down to us. It is also a fact that does cultural-political work.

A municipality whose memory is anchored on objects that are not in the municipality has a structural problem. It cannot point at the Vajralasya in a Butuan museum case and say this is what we were. It cannot walk schoolchildren through the Surigao gold in a Butuan civic display. It can only say this is what we were in language. And the language has to do extra work to compensate for the absence of the objects.

“Kingdom of Butuan” is part of how that work gets done. The phrase is rhetorically larger than the evidence supports because the rhetorical scale is partly compensating for the physical absence of the polity’s anchoring objects from the place that is supposed to remember them. The construct serves a sovereignty function in the absence of the sovereignty objects.

This essay’s argument is not that the phrase should be abandoned by the city or the people who hold it. The municipal-identity work it does is legible and defensible given the artifact-dispersal context. The argument is that the historical-scholarship register can do better — by naming the polity as it actually was, with the precision the evidence supports.

The Mazaua Dispute as Memory Politics

The single sharpest expression of the same dynamic is the Mazaua location dispute.

The site that Antonio Pigafetta calls Mazaua — where the Magellan expedition anchored from 28 March to 4 April 1521, where Pedro de Valderrama celebrated the first Christian Mass in what would become the Philippines on 31 March 1521 — has been the subject of a sustained historiographic and municipal contest for decades.

The National Historical Commission of the Philippines position is that Mazaua = Limasawa, the small island off the southern tip of Southern Leyte. The position is anchored on the navigational-coordinate evidence in Pigafetta’s account, on the Genoese Pilot’s separate record, and on the Albo logbook. The position was reaffirmed by the Mojares Panel (1995–1998), a multi-disciplinary historical investigation convened by the NHCP, and has been reaffirmed by subsequent NHCP rulings.

The Butuan-municipal position is that Mazaua = Masao, in the Agusan delta itself. The position has been advanced by Butuan City, by some Mindanao-based historians, and by the National Quincentennial Commemoration committees that wrestled with the question in 2021.

The Butuan Polities Suite (cycle 63) ran its own test. The suite’s linguistic agent extracted Pigafetta’s Mazaua wordlist — about a hundred items recorded during the 1521 Mazaua-Cebu transit, in Italian orthography — and tested it against modern Surigaonon, Butuanon, Cebuano, Boholano, and South Leyte Visayan reflexes. The test was inconclusive. The diagnostic items (those where the dialectal varieties differ in ways visible through 16th-century Italian-letter transcription) split between the two reading branches. The largest subset of the wordlist is non-diagnostic — Pigafetta’s forms are compatible with both readings.

The honest finding: the wordlist test does not adjudicate Mazaua location. It does not refute the NHCP institutional position; it does not refute the Butuan-municipal position. Sixteenth-century European wordlist transcription of two closely-related Visayan varieties cannot adjudicate between them with the precision the dispute requires.

The suite filed Mazaua as the second of its two irreducible Unknowns and honored the NHCP institutional position as the working position — because the navigational-coordinate evidence on which NHCP rests is outside the suite’s jurisdiction, and because in the absence of a decisive linguistic test the institutional position is what stands. The dispute remains Contested.

What is going on in the dispute, beyond the technical question of where Pigafetta actually anchored, is a memory-politics question. Mazaua is, in the modern Filipino imagination, the foundational landfall of European Christianity in the archipelago. Hosting the Easter Mass of 1521 is a sovereign-cultural claim of enormous weight. The Butuan-municipal advocacy for Masao is, in part, a claim to be the site of that founding moment — a claim that, if granted, would put one of the most symbolically charged events in Philippine national memory back in the polity that the suite has otherwise found dispersed and underdocumented. The Mazaua advocacy is, in the same way as the Kingdom-of-Butuan framing, partly a compensation for the artifact-and-memory absence the polity carries.

This is not a criticism of the advocacy. It is an observation about what is at stake. A municipality whose great artifacts are in Chicago and Manila and Makati would naturally fight, hard, for the foundational European-contact moment to be located on its own shore.

What Honest Scholarship Owes

The Butuan Polities Suite produced, over four cycles, what the convener asked: a defensible reconstruction of the polity at the river’s mouth, anchored on the documentary, material, linguistic, governance, and economic evidence the source record actually delivers. The reconstruction supports a precise reading: a paramount-led trading-port confederation, federated through kinship across the Surigao Strait, deeply integrated into the East Javanese Vajrayana world and the Indianized maritime order, with significant but bounded coastal authority, no jurisdiction over the Manobo and Higaonon and Mamanwa interior partners on whom its prosperity rested, and no documented dynastic continuity across the c. 900–1521 window.

The reconstruction does not support “Kingdom of Butuan” in the modern territorial-sovereignty sense. The reconstruction does not adjudicate the Mazaua location dispute. The reconstruction acknowledges that what we cannot say about the Surigao Treasure assemblage function we will not be able to say from the existing source base.

What honest scholarship owes the polity, on this reading, is a four-part discipline:

Confidence transparency. Every claim in the public-facing piece is tagged with its underlying disposition. Anchored claims are asserted; Probable claims are hedged with “probably” and “the evidence suggests”; Contested claims are presented with the disagreement made visible; Unknown claims are named as Unknown.

Object-provenance honesty. When the Vajralasya is referenced, the citation includes the Field Museum custody. When the Surigao Treasure is referenced, the citation includes the BSP and Ayala custody and the 1981 looted-recovery sequence. When the balangays are referenced, the NMP-distributed custody is named. The custody is part of the polity’s modern existence.

Terminology discipline. Butuan polity, Butuan paramountcy, Butuan trading complex — the working terms in the historical-scholarship register. Kingdom of Butuan used only when discussing the modern construct, the municipal identity, or the historiographic genealogy. The terminology choice is a substantive epistemic choice.

Acknowledgment of memory politics. The artifact-dispersal context, the persistence of the kingdom framing, the Mazaua dispute, the modern municipal advocacy — all of these are part of the polity’s contemporary reality. An essay that pretends to be writing about a 10th- or 14th-century polity in isolation from the 21st-century memory politics that surrounds it is missing half the picture.

The Polity at the River’s Mouth

The polity at the Agusan river-mouth, in the autumn of 1011, sent four chests of Surigao gold and a Cham diplomat and a paramount in a Sanskritic regnal title to the Song court at Quanzhou. The polity at the same river-mouth, in the spring of 1521, received the Magellan expedition with two brothers ruling on opposite sides of the Surigao Strait. The polity in between the two moments traded with China through five centuries of tributary silence, deepened its East Javanese Vajrayana ritual integration, kept building its lashed-lug oceangoing vessels, and provisioned itself in symbiotic exchange with the Manobo and Higaonon and Mamanwa interior whose names appear in no Chinese chronicle and on no Spanish map.

What it was, in the historical-evidence register, is what this series has tried to set out. What it has become, in the modern memory of the city that bears its name, is something else — a memory partly built in compensation for the absence of its objects, partly carried in language because the objects are in Chicago and Manila and Makati, partly contested in the Mazaua advocacy that is also a claim on the most symbolically charged moment of Philippine national memory.

Both registers are real. The honest historical-scholarship register is the one this series has worked in. The modern-memory register is the one that the Butuan-municipal community lives in. They are not the same; they should not be confused; and neither one is more legitimate than the other. The work is to name them clearly and to keep the seam between them visible.

That seam — between what the polity was and what it has become — is the thing this series has tried to read.
