Which U.S. State Once Had Its Own Monarch Before Becoming Part of the United States?

The United States is known for its democratic roots and republican government, but few people realise that one of its states was once ruled by a monarch. The answer to the question — “Which U.S. state once had its own monarch before becoming part of the United States?” — is Hawaii.

Before joining the Union, Hawaii was a sovereign kingdom with its own royal family, government, and international recognition.


The Kingdom of Hawaii – A Royal Past

Long before Hawaii became the 50th state of the United States, it was known as the Kingdom of Hawaii. The kingdom was established in 1810 when King Kamehameha I successfully united the Hawaiian Islands under a single rule.

This marked the beginning of a powerful and independent monarchy that lasted for nearly a century. The Kingdom of Hawaii had treaties with major nations, maintained its own flag, and was recognised internationally as an independent nation.


The Hawaiian Monarchs

The Hawaiian monarchy consisted of a line of rulers who played vital roles in shaping the islands’ history, economy, and culture.

Here’s a brief list of Hawaii’s monarchs:

  1. King Kamehameha I (1810–1819) – United the islands and founded the kingdom.
  2. King Kamehameha II (1819–1824) – Opened Hawaii to foreign influence and trade.
  3. King Kamehameha III (1825–1854) – Introduced Hawaii’s first constitution.
  4. King Kamehameha IV (1855–1863) – Promoted healthcare and education.
  5. King Kamehameha V (1863–1872) – Strengthened royal authority.
  6. King Lunalilo (1873–1874) – Known as “The People’s King.”
  7. King Kalākaua (1874–1891) – Encouraged Hawaiian culture and global relations.
  8. Queen Liliʻuokalani (1891–1893) – The last reigning monarch, overthrown in 1893.

The Overthrow and Annexation of Hawaii

In 1893, Queen Liliʻuokalani was overthrown by a group of American businessmen and sugar planters with the support of U.S. Marines. They established a provisional government, which led to the end of Hawaii’s monarchy.

Five years later, in 1898, Hawaii was officially annexed by the United States under President William McKinley. It became a U.S. territory and, later, the 50th state on August 21, 1959.


Hawaii’s Royal Legacy Today

Although the monarchy was overthrown, the Hawaiian royal heritage still holds a deep place in the hearts of many Hawaiians. The royal palaces, such as ʻIolani Palace in Honolulu — the only royal palace on U.S. soil — stand as a symbol of Hawaii’s proud and independent past.

Hawaiian culture, language, and traditions continue to reflect the influence of its former monarchy.
