People celebrate Columbus Day mainly because it became a U.S. national holiday tied to ideas of exploration, national identity, and especially Italian American pride, not just because of Christopher Columbus himself. In recent decades, it has also become a flashpoint, with many places replacing it or pairing it with Indigenous Peoples’ Day to acknowledge the harms that followed European colonization.

What Columbus Day Was Meant To Celebrate

  • The holiday honors Christopher Columbus’s 1492 voyage, long portrayed in schools as the moment when “the New World” entered European awareness and when “recorded” European-centered history in the Americas began.
  • Supporters describe it as celebrating exploration and the start of sustained contact and cultural exchange between Europe and the Americas, including later waves of European immigration.

Italian American Identity And Patriotism

  • Columbus Day rose in prominence in the late 1800s, when Italian immigrants in the U.S. faced intense discrimination, violence, and stereotypes about being un‑American or inferior.
  • Italian American groups embraced Columbus—an Italian and a Catholic—as a symbol of their contributions and pushed successfully for parades and an official holiday as a statement of belonging and patriotism.

Why It Became A Federal Holiday

  • By the early 20th century, cities were holding big Columbus celebrations, and the figure was woven into school rituals and patriotic narratives, presenting him as a heroic discoverer and symbol of the young nation’s bold spirit.
  • The federal government eventually recognized Columbus Day as a national holiday, putting it alongside other days meant to create shared civic pride and a common national story.

Why It’s Controversial Today

  • Historians and activists emphasize that Columbus’s voyages opened the door to conquest, disease, enslavement, and displacement for Indigenous peoples, challenging the old heroic myth taught to children.
  • Many Indigenous communities and allies argue that celebrating Columbus erases that suffering, so they advocate renaming the day or shifting focus to Indigenous resilience, cultures, and rights.

Current Trends: Columbus Day And Indigenous Peoples’ Day

  • A growing number of U.S. cities, states, and institutions now mark Indigenous Peoples’ Day instead of, or alongside, Columbus Day, trying to balance older traditions with a more critical view of history.
  • Public debate continues in news outlets and online forums, with some seeing dual observances as a compromise, others wanting a full replacement, and still others defending Columbus Day as a core ethnic and national symbol.

TL;DR: People celebrate Columbus Day because it became a patriotic and Italian American heritage holiday built around an older heroic story of Columbus and “discovery.” Today, that story is hotly debated, and many places are shifting toward Indigenous Peoples’ Day to center Indigenous history and the realities of colonization.
