Cisplatine Province was a historical region in South America, primarily located in what is now Uruguay. Established in the early 19th century, it was part of the larger Viceroyalty of the Río de la Plata. The province was named after the Rio de la Plata, which means "River of Silver," and it played a significant role in the region's early struggles for independence. The province was officially created in 1811 and existed until 1828 when it became the independent nation of Uruguay. Its capital was Montevideo, which remains the capital of Uruguay today. The area was characterized by its diverse population and rich cultural heritage, influenced by Spanish, Portuguese, and indigenous peoples.
