Simula is a programming language developed around 1965 by Norwegian computer engineers Kristen Nygaard and Ole-Johan Dahl. Simula is based on the language ALGOL 60, and its purpose was the simulation of complex computing systems. Simula was the first programming language to use objects, classes, subclasses, and inheritance, and is considered to be the first object-oriented programming language.
