When Ponce de León arrived in Puerto Rico, he was well received by the "Cacique" (Tribal chief) Agüeybaná (The Great Sun), chieftain of the island Taino tribes. Besides the conquistadors, some of the first colonists were farmers and miners in search of gold. In 1508, Ponce de León became the first appointed governor of Puerto Rico, founding the first settlement of Caparra between the modern-day cities of Bayamón and San Juan. After being named Governor, de León and the conquistadors forced the Tainos to work in the mines and to build fortifications; many Tainos died as a result of cruel treatment during their labor. In 1510, upon Agüeybaná's death, his brother Güeybaná, better known as Agüeybaná II (The Brave), and a group of Tainos led Diego Salcedo, a Spaniard, to a river and drowned him, proving to his people that the white men were not gods. Upon realizing this, Agüeybaná II led his people in the Taino rebellion of 1511, the first rebellion in the island against the better armed Spanish forces. Guarionex, cacique of Utuado, attacked the village of Sotomayor (present-day Aguada) and killed eighty of its inhabitants. Cacique Guarionex died during the attack which was considered a Taino victory.
