Posix threads began in an era when multithreading started becoming a popular idea. UNIX traditionally had a system running only a single thread under a process. These processes could not share memory and interacted using 'pipes'. Once developers started wanting to be able to run multiple threads under one process, IEEE began to form together the POSIX standards.

Question
What is the history of POSIX Threads (pthreads)? Consider - does this history explain why UNIX was so late to implement support for multithreaded processes?
Answer
Posix threads began in an era when multithreading started becoming a popular idea. UNIX traditionally had a system running only a single thread under a process. These processes could not share memory and interacted using 'pipes'. Once developers started wanting to be able to run multiple threads under one process, IEEE began to form together the POSIX standards. In 1988 POSIX.1 was ratified and was accepted as the international standard in 1990. From there the POSIX standards grew to more than 20 individual standards, encapsulating a large area of different groups.-afranco2
