From 1581-1976

Spain and Portugal were once a United Kingdom

Spain was United Under one banner with the marriage or Aragon and Isabel of Castile

Went On to Over through Muslim rule over Spain wohooo

The Spanish Over extended and Had many wars like every other empire

Modern Liberation Movements were getting stronger with the help of the United States so it Could be the next world power

Seriously how can you compete with issue number 2 you cant beat US back movements Unless your Iran

So ends the Spanish Empire
