December 29: Becket's Martyrdom, Texas Joins, and Japan Arms

December 29 marks three moments when power struggles reshaped history—when a friendship between king and archbishop ended in blood on cathedral stones, when a vast republic joined the American union and ignited controversy, and when a rising power abandoned restraint for expansion. These stories remind us that history pivots on conflicts between loyalty and principle, between caution and ambition, and between the constraints we accept and those we reject.

Murder in the Cathedral

On December 29, 1170, four knights burst into Canterbury Cathedral where Thomas Becket, Archbishop of Canterbury, was preparing for vespers. They had ridden from King Henry II's court in France, believing they were carrying out the king's wishes after Henry allegedly exclaimed in frustration, "Will no one rid me of this turbulent priest?" The knights cornered Becket near the altar. When he refused to flee or submit, they struck him down with swords, scattering his brains across the cathedral floor. The murder of an archbishop in his own church shocked medieval Europe—it was sacrilege compounded by political violence, transforming Becket instantly from troublesome prelate to martyr whose blood stained the stones where pilgrims would soon pray.

Becket's death climaxed a bitter dispute between church and crown. Henry had appointed his friend Thomas as archbishop, expecting loyalty; instead, Becket championed church independence from royal authority with convert's zeal. Their conflict over clerical immunity, church courts, and ecclesiastical appointments represented the medieval struggle between secular and spiritual power—who ultimately ruled Christian society, kings or church? Becket's murder backfired spectacularly for Henry: the archbishop was canonized within three years, Canterbury became Christianity's most important English pilgrimage site, and Henry was forced to do public penance, walking barefoot through Canterbury while monks flogged him. The "turbulent priest" achieved in death what he couldn't in life—demonstrating that church authority transcended royal power, that some principles were worth dying for, and that martyrdom could defeat monarchy. December 29, 1170, reminds us that friendships founded on mistaken expectations can end in tragedy, that power struggles between institutions can turn personal and violent, and that sometimes blood spilled in the name of principle transforms defeat into victory. Becket's murder didn't settle the church-state conflict—it continues still—but it proved that moral authority, sealed by martyrdom, can outlast any king's sword.

The Lone Star Joins the Union

Six hundred seventy-five years after Becket's murder, on December 29, 1845, Texas officially became the 28th state of the United States—the culmination of a controversial annexation that had sparked fierce debate and nearly triggered war with Mexico. Texas had won independence from Mexico in 1836, establishing itself as a sovereign republic with its own president, congress, and foreign relations. For nine years, the Lone Star Republic existed in limbo—too large and important to ignore, too controversial to admit to the Union. The controversy centered on slavery: Texas would enter as a slave state, upsetting the carefully maintained balance between free and slave states that kept sectional tensions from erupting into conflict.

President John Tyler pushed annexation through Congress in the final days of his presidency using a joint resolution that required only a simple majority rather than the two-thirds needed for a treaty. Mexico, which had never recognized Texas independence, warned that annexation meant war. President James K. Polk, an ardent expansionist, welcomed Texas anyway, and Mexico made good on its threat—the Mexican-American War erupted in 1846, resulting in American acquisition of California and the Southwest. Texas statehood thus triggered territorial expansion that brought the United States to the Pacific but also intensified the slavery debate that would tear the nation apart. December 29, 1845, demonstrates that expansion and controversy are often inseparable, that adding territory doesn't resolve conflicts but can exacerbate them, and that today's bold achievement can become tomorrow's crisis. Texas joined the Union carrying both promise and problems—vast territory and resources but also slavery's expansion and war's inevitability. The Lone Star became one star among many, but it brought with it complications that would help push America toward civil war within fifteen years.

The Constraints Cast Aside

Eighty-nine years after Texas statehood, on December 29, 1934, Japan formally withdrew from the Washington Naval Treaty, abandoning the international arms limitation agreement that had maintained naval balance among major powers since 1922. The treaty had emerged from the devastation of World War I, when nations recognized that unchecked military competition bred conflict. It limited battleship construction and established tonnage ratios designed to prevent naval arms races: the United States and Britain could each have navies of 525,000 tons, Japan 315,000, and France and Italy 175,000 each. Japan had reluctantly accepted the lower ratio, viewing it as Western nations treating them as inferior. By the 1930s, militarists dominated Japanese politics, arguing that naval limitations prevented Japan from securing the resources and territory it needed.

Japan's withdrawal signaled that the era of negotiated disarmament had ended and that imperial ambitions now trumped diplomatic restraint. The move freed Japan to build the massive fleet it would use to attack Pearl Harbor seven years later, initiating the Pacific War. The treaty's collapse demonstrated that arms control agreements only work when nations value stability over expansion—once a power decides constraints limit rather than protect it, paper agreements become worthless. Japan's decision reflected broader interwar trends: the League of Nations failing, Germany rearming, and international cooperation crumbling as nationalism and militarism rose. December 29, 1934, marked a turning point when diplomacy gave way to preparation for conflict, when one nation's rejection of limits began unraveling the fragile peace holding since World War I. The withdrawal reminds us that international order requires not just treaties but commitment to the values underlying them, that arms limitation only succeeds when nations believe security comes through cooperation rather than domination, and that when major powers abandon restraint, the world inevitably slides toward war. Within eleven years, the unconstrained naval power Japan built would lie at the bottom of the Pacific, a testament to how rejecting limits in pursuit of empire can end in catastrophic defeat.
