Mathematics did not suddenly appear in a textbook. People developed it over thousands of years because they had real problems they needed to solve.
Ancient mathematicians developed methods for finding areas, volumes and approximations that anticipated important ideas of integral calculus.
Eudoxus and Archimedes used exhaustion methods to determine areas and volumes by repeatedly refining geometric approximations.
Mathematicians in India, the Islamic world and Europe developed series, geometric methods and ideas about changing quantities that helped prepare the way for calculus.
Isaac Newton and Gottfried Wilhelm Leibniz independently developed systematic forms of calculus. Leibniz introduced notation that remains widely used today.
Euler, Cauchy, Weierstrass and many others expanded calculus and placed limits, continuity and infinite processes on increasingly rigorous foundations.
Calculus became foundational to physics, engineering, economics, statistics, computing, biology and nearly every quantitative science.
Modern technology uses calculus in simulation, machine learning, robotics, aerospace engineering, medicine, finance and optimization.
