Spain has a varied landscape due to its mountainous terrain and varied weather. Its geography and strategic location have led to cultural diversity from many invading and colonizing peoples throughout history such as the Phoenicians, Greeks, Romans, Visigoths, and Muslims. Spain built a vast empire in the 1500s and 1600s after the discovery of America, leading to a golden age of Spanish culture, though it later declined and lost its colonies. After a civil war in the 1930s and dictatorship until the 1970s, Spain transitioned to democracy and joined the European Union in 1986. Today it has a population of 46 million and is a top tourist and fishing country known for its diverse regions, festivals, and cuisine.
