Spain went from being a powerhouse to a flop when they kicked out the Muslims and Jews
Hmmmm. Are you sure of this?
Spain was a Roman province. You have probably seen the movie Gladiator, Maximo Decimo Meridio lived in Emerita Augusta, capital of Lusitania, one of the largest Roman provinces of Hispania, today known as
Mérida, after that was invaded by Goths, Visigoths, etc. During the years 711 to 726 was in turn invaded by Muslims. "La Reconquista" (reconqueror), or process in which Spaniards begin to recover their territory against Muslim invaders starts at 722 and ends at 1492 with the fall of the kingdom of Granada.
The expulsion of the Jews from Spain in 1492 was ordered by the Catholic Monarchs. [Notice the years].
It was the October 12, 1492 when Christopher Columbus at the service of Spain discoveres America. What this man was looking for was an alternate trade route between Spain and India to avoid tolls, relying on the idea that the Earth was round. When he arrived at America he thought he had reached India and called the natives Indians. In fact died without knowing that he had discovered a new continent.
In 1494 Spain and Portugal divided the New World with the
Treaty of Tordesillas with the blessing of then Pope. A dividing line to the left for Spain, the rest was drawn to Portugal. In such a way that what it is now known as Brazil was to the right of this dividing line and became part of Portugal.
During the reign of Philip II (king of Spain from 1527 to 1598) the famous phrase "In Spain the sun never sets," he said. Referring to the number of territories that became pertener to Spain: from America to the Philippines. In fact, the name of Phhilippines was in honor of Philip II.
The Spanish Golden Age spans two centuries: XVI and XVII [Notice the years]. One of the last colonies to take independence was Cuba in 1895, long time after the expulsion of Muslims and Jews.
I do not follow much more. The decline of Spain is due to the enormous costs that kept stupid wars and mismanagement.
It is incomprehensible that expelled the Jews from Spain for religious reasons, but the issue of Muslims was a simple matter of reconquest.
