A microkernel is one kind of a kernel implementation.
Liedtke explains in On Microkernel Construction* that a microkernel attempts to minimize the mandatory part of the operating system by providing the minimal number of mechanisms that maximize the flexibility of implementation (by imposing minimal policy) while allowing the efficient implementation of the remainder of the system.
The idea of a microkernel as explained above was first explored by Per Brinch-Hansen in 1970 in The Nucleus of a Multiprogramming System.
