Barbados stopped pledging allegiance to Queen Elizabeth II on Tuesday as it shed other remains of its colonial past and became a republic for the first time in history.

Several leaders, dignitaries and artists, including Prince Charles and Rihanna, attended the ceremony that began late Monday in a popular square where the statue of a well-known British lord was removed last year amid a worldwide push to erase symbols of oppression.

The drive to become a republic began more than two decades ago and culminated with the island’s Parliament electing its first-ever president last month in a two-thirds majority vote.

Barbados Governor General Sandra Mason was sworn in before dawn on Tuesday as the island marked its 55th anniversary of independence from Britain.

Mason, 72, is an attorney and judge who also has served as ambassador to Venezuela, Colombia, Chile and Brazil. She will help Prime Minister Mia Mottley lead the wealthy Caribbean island of more than 300,000 people that is dependent on tourism, manufacturing and finance.

Barbados didn’t need permission from the U.K. to become a republic, although the island will remain a member of the Commonwealth Realm. It’s an event that the Caribbean hasn’t experienced since the 1970s, when Guyana, Dominica and Trinidad and Tobago became republics.

Barbados became independent from the United Kingdom in November 1966, more than three centuries after English settlers arrived and turned the island into a wealthy sugar colony based on the work of hundreds of thousands of African slaves.

In 2005, Barbados dropped the London-based Privy Council and chose the Trinidad-based Caribbean Court of Justice as its final court of appeal.

Last year, Barbados announced plans to stop being a constitutional monarchy and removed a statue of British Vice-Admiral Horatio Nelson from National Heroes Square, the location of the event to celebrate becoming a republic.

Speaking at the event, Prince Charles, thanked Barbadian officials for inviting him and said he has greatly admired what they’ve achieved. He said:

From the darkest days of our past and the appalling atrocity of slavery, which forever stains our history, the people of this island forged their path with extraordinary fortitude. Freedom, justice, and self-determination have been your guides.

Barbados’ flag, coat of arms and national anthem will remain the same, but certain references like “royal” and “crown” will no longer be used.
