Before 1898, Spain had had the colony of the Philippines for a long time. However, after the Spanish-American war, it gave that colony over to the United States, which caused it to get politically involved with the Philippines.

Florence enjoyed a flourishing of the arts in the 1400s. Many artists moved to Florence because there was a market for the purchase of their artwork. The upper and middle class of merchants and bankers were very wealthy and they wanted to enjoy the pleasures of life on earth, not just focus on the afterlife. This created a gap in the market for quality artworks and music concerts etc. Artists, musicians and poets moved to Florence to fill this gap in the market.
