Northern Ireland is a part of the United Kingdom of Great Britain. In contrast, the southern portion of Ireland (the Republic of Ireland) is its own country.
Ireland owns itself. It is an independent country. You are confusing Ireland with Nothern Ireland, which are different things. Northern Ireland is part of the United Kingdom. Ireland, officially called Éire and sometimes called the Republic of Ireland is independent. Both Ireland and Northern Ireland are on the island that also has the name Ireland.
northern Ireland is governed by England and it's part of the UK , although it is of course owned by the Irish people

The United Kingdom is a sovereign nation. It is a union between four countries (England, Wales, Scotland, and Northern Ireland) that are then constituent countries due to the sovereignty of the UK as a whole. Due to the UK being a country, nothing owns the UK. The United Kingdom owns itself.
