The story begins in the 12th century when Afonso Henriques, the first king of Portugal, decided to make Lisbon the capital. This was a big deal, as it was a strategic location that connected the country to the rest of Europe and the Atlantic. It's kind of like choosing the perfect spot for your favorite coffee shop - you want it to be central and easy to get to!
Before Lisbon, the capital was actually Guimarães, a city in the north of Portugal. But, as the country started to grow and trade with other nations, Lisbon's harbor became a major hub, making it the perfect spot for the new capital. It's similar to how you might choose a new restaurant to try - you look for the one with the best reviews and the most convenient location!
