Honolulu the capital and the most populous city of the U.S. state of Hawaii.a Honolulu is the southernmost major U.S. city. Although the name "Honolulu" refers to the urban area on the southeastern shore of the island of Oahu, the city and county government are consolidated as the City and County of Honolulu which covers the entire island. For statistical purposes, the U.S. Census Bureau recognizes the urban part of Honolulu as a census-designated place.
The city has been the capital of the Hawaiian islands since 1845 and gained historical recognition following the Japanese attack on Pearl Harbor near the city on December 7, 1941, and as the birthplace of Barack Obama, the 44th and current President of the United States.
Evidence of the first settlement of Honolulu by the original Polynesian migrants to the archipelago comes from oral histories and artifacts. These indicate that there was a settlement where Honolulu now stands in the 11th century. However, after Kamehameha I conquered Oʻahu in the Battle of Nuʻuanu at Nuʻuanu Pali, he moved his royal court from the Island of Hawaiʻi to Waikīkī in 1804. His court relocated in 1809 to what is now downtown Honolulu. capital was moved back to Kailua-Kona in 1812.
In 1794, Captain William Brown of Great Britain was the first foreigner to sail into what is now Honolulu Harbor. More foreign ships followed, making the port of Honolulu a focal point for merchant ships traveling between North America and Asia.
The UK consulting firm Mercer, in a 2009 assessment "conducted to help governments and major companies place employees on international assignments", ranked Honolulu 29th worldwide in quality of living; the survey factored in political stability, personal freedom, sanitation, crime, housing, the natural environment, recreation, banking facilities, availability of consumer goods, education, and public services including transportation.

The Honolulu District is located on the southeast coast of Oahu between Makapuu and Halawa. The district boundary follows the Koolau crestline, so Makapuu Beach is in the Koolaupoko District. On the west, the district boundary follows Halawa Stream, then crosses Red Hill and runs just west of Aliamanu Crater, so that Aloha Stadium, Pearl Harbor (with the USS Arizona Memorial), and Hickam Air Force Base are actually all located in the island's Ewa District.
The Hawaii Department of Public Safety operates the Oahu Community Correctional Center, the jail for the island of Oahu, in Honolulu CDP.
