   “Columbus Day is a national holiday in many countries of the Americas and elsewhere, and a federal holiday in the United States. It officially celebrates the anniversary of the arrival of Christopher Columbus in the Americas. He went ashore at Guanahaní, an island in the Bahamas, on October 12, 1492 [OS]. He built La Navidad on the northwestern coast of the island of Hispaniola (near present-day Caracol, Nord-Est Department, Haiti) in late December 1492, the first European fort in the Americas. After the destruction of the fort by the indigenous Taíno people, Columbus established La Isabela on the central-northern coast of the island (now present-day Dominican Republic) in late December 1493, the first stable European settlement in the Americas. Christopher Columbus (Italian: Cristoforo Colombo [kriˈstɔːforo koˈlombo]) was an Italian explorer from Genoa, who led a Spanish maritime expedition to cross the Atlantic Ocean in search of an alternative route to the Far East. Columbus believed he sailed his crew to the East Indies, but Europeans realized years later that his voyages landed them in the New World.”

   Indigenous Peoples' Day (United States) (Wikipedia)

   WikipediaPublished Oct 12, 2026Checked Oct 12, 2026

   “Indigenous Peoples' Day is an official city and state holiday in various localities in the United States that celebrates and honors Indigenous American people (Native Americans) and commemorates their histories and cultures. It is celebrated on the second Monday in October. It began as a counter-celebration held on the same day as the U.S. federal holiday of Columbus Day, which honors Italian explorer Christopher Columbus. It is celebrated as an alternative to Columbus Day, citing the lasting harm Indigenous tribes suffered because of Columbus's contributions to the European colonization of the Americas. The roots of the holiday can be traced back to discussions and propositions regarding instituting it as a replacement for Columbus Day that took place in 1977 during The International NGO Conference on Discrimination Against Indigenous Populations in the Americas in Geneva, Switzerland. In 2021, Joe Biden formally commemorated the holiday with a presidential proclamation, becoming the first U.S. president to do so, and presidential proclamations have also been issued in 2022, 2023, and 2024.”

   Polarizing trajectories of colonial ideologies: A latent class growth analysis of historical negation and symbolic exclusion.

   The British journal of social psychology (Bertenshaw et al.)Published Oct 1, 2026Checked Oct 12, 2026

   “The impassioned advocacy both for and against Indigenous rights in recent years suggests a polarization of public opinion. Accordingly, we theorize increasingly divided endorsement of two ideologies that challenge Indigenous rights to material and symbolic equality-historical negation and symbolic exclusion, respectively (the 'Dark Duo'). Using latent class growth analysis, we test for distinct classes of change in the Dark Duo over 16 years (2009-2025) among a national probability sample of New Zealand adults (N = 43,020). As expected, results reveal a subgroup of Progressives (76.84%) with lower levels of historical negation and symbolic exclusion that decreased over time and a smaller subgroup of Reactionaries (23.16%) with higher levels of these ideologies that increased over the same period. Demographic and socio-political variables predicted class membership, and support for political parties varied across classes. Thus, the current study illustrates the presence and implications of ideological polarization towards Indigenous rights.”
