The history of the Hungarian Kings dates back to the founding of the Kingdom of Hungary in 1000 AD, when Stephen I was crowned as the first king. He played a crucial role in establishing Christianity in Hungary and is now regarded as a national saint. Over the centuries, various dynasties, such as the Árpád dynasty and the Angevin dynasty, ruled the kingdom, each contributing to Hungary's cultural and political development. The monarchy continued until the early 20th century, with the last king being Charles IV. Following World War I and the dissolution of the Austro-Hungarian Empire, Hungary transitioned to a republic, ending the era of the Hungarian Kings.
