N2  - Many aspects of star cluster formation and evolution are unconstrained. This thesis presents models of star cluster formation ? including gas and stellar dynamics, sub-grid star formation, stellar evolution, and stellar feedback ? from turbulent gas clouds of initial mass 10?, 10?, and 10? M?. The latter is one of the largest star-by-star cluster models to date and has provided many new insights into the formation and early evolutionary properties of young massive star clusters. First, I examine the global properties of each cloud, particularly noting the high star formation efficiency. In sufficiently dense and massive clus- ters, stellar feedback is unable to quench star formation as gravity overpowers it. Next, I identify a novel mechanism for the production of runaway stars in young clusters, the sub-cluster ejection scenario, in which a subset of stars in an infalling sub-cluster are ejected by a tidal interaction with the assembling cluster?s center of mass. Lastly, I analyze the presence of dynamical mass segregation in the models, where massive stars are more centrally clustered than low-mass stars. These models have no primordial mass segregation by construction. Young clusters can undergo early dynamical mass segregation during core collapse when the crossing time is substantially reduced.
