Pope Gregory XI returns the Papacy from Avignon to Rome, ending the Avignon Papacy.
On January 17, 1377, Pope Gregory XI arrives in Rome, bringing an end to nearly 70 years of Papal residence in Avignon.

France grants religious toleration to the Huguenots in the Edict of Saint-Germain.
France issues the Edict of Saint-Germain, granting limited religious toleration to the Huguenots.
On January 17, 1562, King Charles IX of France promulgates the Edict of Saint-Germain, offering official toleration to the Protestant Huguenots. The decree represents the first royal attempt to ease religious tensions in a kingdom torn by confessional conflict. While Catholics view the edict with suspicion, Huguenot leaders see it as a crucial step toward legal recognition. The compromise fails to prevent the outbreak of the French Wars of Religion later that year. Nonetheless, the edict introduces principles of coexistence that influence future attempts at religious peace. It stands as an early milestone in Europe’s struggle for freedom of conscience.

The United States takes possession of Wake Island in the Pacific Ocean.
The United States formally annexes Wake Island, expanding its strategic presence in the Pacific at the turn of the century.
On January 17, 1899, U.S. naval officers raised the American flag over Wake Island, asserting sovereignty over the remote atoll. The acquisition aimed to establish a coaling station and naval base along emerging Pacific trade routes. Wake Island's strategic location between Honolulu and Guam proved valuable for future military and communication purposes. Despite its harsh coral terrain, the island would later host key installations during World War II. The annexation exemplified the United States' growing imperial reach following the Spanish-American War. Wake Island remains an unincorporated territory of the U.S., a testament to 19th-century expansionism.

The Renville Agreement between the Netherlands and Indonesia is ratified.
The Renville Agreement, defining ceasefire lines between the Netherlands and Indonesia, was ratified, shaping early Indonesian independence.
On January 17, 1948, the Netherlands ratified the Renville Agreement with the Indonesian republic, seeking to halt hostilities in the Indonesian National Revolution. Negotiated aboard the USS Renville in December 1947, the pact established military demarcation lines and temporary governance arrangements. The agreement acknowledged Republican authority in certain regions while recognizing Dutch control elsewhere. Although intended to create stability, it failed to address the core issue of full sovereignty, leading to renewed clashes. Both sides accused each other of violations, and the Renville Agreement ultimately delayed but did not prevent further conflict. Nonetheless, it represented a significant diplomatic effort in Indonesia’s struggle for independence.
