The surname was often used to identify individuals who lived in a particular house or estate or were associated with a notable residence.

During the 15th and 16th centuries, the surname Casas gained prominence as Spain expanded its territories and influence through exploration and colonization. Several historical figures with the surname Casas emerged during this period, including Bartolomé de las Casas (1484-1566), a Spanish Dominican friar and historian known for his advocacy for the rights of indigenous peoples in the Americas.

Another notable individual with the surname Casas was Juan de las Casas (1498-1558), a Spanish conquistador who accompanied Hernán Cortés in the conquest of Mexico. He later served as the governor of Chiapas, a state in southern Mexico.

In the 17th century, the surname Casas was carried to various parts of the Spanish Empire, including the Americas and the Philippines. One prominent figure from this era was Cristóbal de las Casas (1598-1672), a Spanish Jesuit missionary and linguist who worked extensively with indigenous communities in Mexico.

As the Spanish Empire expanded, the surname Casas spread to other regions, including the Caribbean and South America. In the 18th century, José María de las Casas (1743-1802), a Spanish military officer and colonial administrator, served as the governor of Cuba from 1790 to 1796.

The surname Casas has also been associated with various place names throughout Spain and its former territories. For example, the town of Casas de Don Pedro in the province of Badajoz, Spain, is believed to have derived its name from a historical figure with the surname Casas.
