Why did Renaissance appear Italy first of all ?

1. Fall of Constantinople : After the fall of Constantinople the learned Christian scholars were persecuted by the Turks and forced to flee to Italy, the seat of Pope.
These scholars had reached Italy via Greece and and had brought good books of that country. This helped in the spreading of Greek Knowledge in Italy.

2. Fall of Feudalism : It helped in the emergence of new towns and cities. Greek scholars were welcomed there.

3. Topographical Location of Italy: Italy is situated half way between the Western Europe and the Middle East. The Italian cities were centres of prosperous trade and commerce and encouraged Greek scholars. So Renaissance was the first to appear in Italy.
