Ireland split from Northern Ireland due to historical and political reasons. The split occurred in 1921 when the Anglo-Irish Treaty was signed, leading to the creation of the Irish Free State (now the Republic of Ireland) and Northern Ireland as part of the United Kingdom. The split was a result of the Irish War of Independence and the desire for Irish independence from British rule. The predominantly Catholic population in Ireland sought independence and self-governance, while the predominantly Protestant population in Northern Ireland wanted to remain part of the United Kingdom. This division led to the establishment of separate governments and ultimately the split between Ireland and Northern Ireland. **
