The Spanish kingdom was created in 1492 and began its empire through Columbus' voyage to the New World. For the next three centuries, Spain was the most powerful colonial power, though wars with other European nations led to economic decline by the 17th century. The Spanish Empire dominated oceans and battlefields in the 16th century as one of the first global empires, bringing Christianity throughout its expansion, before experiencing a cultural golden age and eventual decline under the Habsburgs in the 16th-17th centuries.
