Spanish was introduced in the islands after 1565, when the Spanish conquistador Miguel López de Legazpi set sail from Mexico and founded the first Spanish settlement on Cebú. Though its usage is not as widespread as before, Spanish has had a significant influence in the various local Philippine languages such as providing numerous loan words. Several Spanish-based creole language varieties collectively known as Chabacano have also emerged. The current 1987 constitution makes mention of Spanish in which it provides that Spanish (along with Arabic) is to be promoted on an optional and voluntary basis.
