The first uses of hydraulics can be traced back to the 6000's B.C. when water was used to power irrigation systems by the ancient Mesopotamians and Egyptians. Several centuries later in 1647, Pascal's Law was discoverd.

The industrial revolution helped expand its use cases even further and in the late 1800s some of the first pieces of construction equipment and other heavy machinery started using hydraulics. Use of hydraulics only grew from there. When Power & Motion, originally called Applied Hydraulics, was started in 1948, it was stated in the editor's letter that after utilizing hydraulics in the majority of planes built for World War II that much was learned about the technology and how it could be applied in a range of other industries.

Since the earliest uses of hydraulics — the transmission of power via pressurized fluid, typically oil but sometimes water — the technology has continued to advance and evolve. Today there is ever greater integration of electronics and communication protocols to help improve hydraulic system performance.

HAWE Hydraulik said it expects this trend to continue in the coming decades as well as efforts to enable higher operating pressures and increased focus on improving the energy efficiency of hydraulic systems.

As Moog Inc. stated to Power & Motion, the hydraulics industry has evolved from simple mechanical feedback servo valves to electro-hydraulic solutions to fully electric power and motion control applications as the market and customer requirements have changed.
