Aberdeen is a city in Northeast Scotland, located on the North Sea coast. It is the third most populous city in Scotland, after Glasgow and Edinburgh. The city has a long and rich history, dating back to the 11th century when it was first established as a royal burgh by King William the Lion.
The city was an important trading port in the Middle Ages, and was the site of the Battle of Aberdeen in 1296, when the English defeated the Scots. In the 16th century, Aberdeen became a major centre for the fishing industry, and the city's harbour was expanded to accommodate the growing number of ships.
In the 19th century, Aberdeen was a major centre for the oil and gas industry, and the city's population grew rapidly. The city was also the birthplace of the North Sea oil industry, and the first oil rig was built in Aberdeen in the 1970s.
Today, Aberdeen is a vibrant and modern city, with a thriving economy and a rich cultural heritage. The city is home to a number of universities, museums, galleries, and theatres, and is a popular tourist destination.
