Trapezium type multiple stars are centers of star formation in stellar associations. Theoretical and observational studies show that they are dynamically instable. Due to the special space configurations of the components, Trapezium type multiple stars disintegrate completely or partly after several rotations around their centers. These stars have a main role in the origin and evolution of stars on OB- and T-associations. According to observations of 15 Trapezium type multiple stars having the brightest star of OB-class 14 are in expansion. The age of the Trapezium type multiple stars is of the order of 21(P years. There are weighty arguments to assume that the majority of them are in a state of expansion with positive total energy.
