With 780,995 residents as of 2024, it ranks as the 18th most populated city in the US. However, with more than 4.15 million inhabitants, the Seattle metropolitan region ranks as the 15th most populated metropolitan area in the US. King County, Washington's most populated the county, has its county seat in the city. Seattle was one of the fastest-growing big cities in the nation, with a growth rate of 21.1% between 2010 and 2020. Seattle is located on an isthmus that separates Lake Washington from Puget Sound, a Pacific Ocean inlet. Situated roughly 100 miles (160 km) south of the Canadian border, it is the northernmost major city in the United States. As of 2021, the Port of Seattle, which serves as a gateway for trade with East Asia, ranked fourth in North America for container handling. Before the first permanent European settlers arrived, Native Americans (including the Duwamish, who had at least 17 communities surrounding Elliot Bay) had lived in the Seattle area for at least 4,000 years.14 On November 13, 1851, Arthur A. Denny and his party of travelers—later dubbed the Denny Party—arrived at Alki Point on the schooner Exact from Illinois via Portland, Oregon.Named ""Seattle"" for Chief Seattle, a notable 19th-century chief of the nearby Duwamish and Suquamish tribes, the settlement was relocated to Elliott Bay's eastern side in 1852.

Cairo isn’t just the capital of Egypt — it’s the pulse of the nation. A city where ancient history meets modern chaos, where the call to prayer rises above the traffic, and where every alley seems to hum with life. Home to over 10 million people, Cairo is one of the biggest and most energetic cities in the Middle East and Africa. It’s a place of contrasts — the timeless Pyramids of Giza just a short drive from bustling markets, rooftop cafés, and shiny new malls. The Greater Cairo Metropolitan Area, with more than 22 million residents, is among the most populated urban regions on Earth. Surrounded by ancient sites like Memphis, Heliopolis, and the Giza Plateau, Cairo is a living bridge between Egypt’s past and its future. The city’s origins trace back to Fustat, Egypt’s first Islamic capital founded in 641 CE, and later to 969 CE, when the Fatimid dynasty created what we now call Cairo. Through centuries — under the Ayyubids, Mamluks, and beyond — the city became Egypt’s heart of architecture, art, and learning.
