What city became the steel making capital of the world?

Pittsburgh, Pennsylvania, became known as the steel-making capital of the world during the late 19th and early 20th centuries. The city's strategic location near coal and iron ore resources, combined with the rise of the steel industry, particularly with companies like Carnegie Steel, contributed to its dominance in steel production. This industrial boom played a pivotal role in shaping the city's economy and workforce. Today, Pittsburgh has diversified its economy but retains its historical legacy in steel manufacturing.
