Globular cluster (GC) systems can be used as powerful tools to investigate the evolutionary history of early-type galaxies. In this thesis, we study the GC systems of five early-type galaxies in which first investigation for four galaxies using wide-field imaging data. All GC systems show a clear distribution of blue and red GCs. Also, we explore their radial density, colour and azimuthal distributions. We find a dependence of the relative fraction of blue to red GCs with host galaxy environmental density for lenticular galaxies. A one-to-one relation between the ellipticities of red GCs and the galaxy stellar light emphasises the evolutionary similarities between them.
