Yerba Buena, California is renamed San Francisco, California.

On January 30, 1847, the settlement of Yerba Buena in Alta California was officially renamed San Francisco, reflecting its growing prominence and strategic harbor.
In the midst of the Mexican–American War and American settlement of California, the small pueblo of Yerba Buena underwent a symbolic transformation. On January 30, 1847, municipal authorities adopted the name San Francisco, honoring the nearby bay and the Spanish mission established in 1776. This change signified the region's shift from a Mexican outpost to an Americanizing community. The new name aligned the town with the bay's strategic harbor, fostering trade and immigration. San Francisco rapidly grew during the Gold Rush just two years later, evolving into a major port city. Today, the 1847 renaming marks the humble origins of one of America's most iconic cities.

Indian pacifist and leader Mohandas Karamchand Gandhi is released from prison by Jan C. Smuts after being tried and sentenced to two months in jail earlier in the month.

Mohandas Karamchand Gandhi was released from prison in South Africa in 1908 after serving two months for leading passive resistance campaigns.
In January 1908, Indian lawyer and activist Mohandas Karamchand Gandhi was freed from Pretoria's Marshall Square Prison after completing a two-month sentence. Gandhi had been arrested for organizing nonviolent protests against discriminatory laws targeting the Indian community in South Africa. His imprisonment only strengthened his commitment to Satyagraha, the philosophy of nonviolent resistance. British statesman Jan C. Smuts authorized his release, recognizing Gandhi's moral authority and leadership potential. This period marked a crucial turning point in Gandhi's transformation into a global icon of civil disobedience. His experiences in South Africa laid the foundation for the mass movements he would later lead in India's struggle for independence.

The Government of Turkey expels Patriarch Constantine VI from Istanbul.

In 1925, the secular Turkish government expelled Patriarch Constantine VI, the Ecumenical Patriarch of Constantinople, from Istanbul.
Following the establishment of the Republic of Turkey in 1923 under Mustafa Kemal Atatürk, the new government pursued aggressive secularization and nationalization policies. On January 30, 1925, Patriarch Constantine VI was declared persona non grata and forced to leave Istanbul. He was relocated to the nearby Princes’ Islands, effectively severing the historic seat of the Ecumenical Patriarchate from its traditional base. This expulsion reflected Ankara’s determination to curtail foreign influence in religious affairs and assert state control over religious institutions. The move drew protests from Orthodox Christian communities worldwide, who saw it as an infringement on religious freedom. It underscored the tension between the Republic’s modernization efforts and the centuries-old religious heritage of the city. The event foreshadowed further restrictions on non-Muslim minorities throughout the decade.
