The abundance  of X-ray binaries in  our and other  Galaxies and their brightness at many  wavelengths make them key to  our understanding of different  physical  processes   (accretion  and  gravitational  waves radiation) and of advanced  questions in stellar evolution (the origin and evolution  of binary systems,  the final stages of  massive stars, the  formation   of  compact   objects).   Within  the   next  decade, observations  at  existing  and   planned  facilities  in  almost  all wavelengths  will put  a heavy  demand on  further studies  of compact binaries. In my talk, I will  discuss what is our current knowledge of low-mass  X-ray  binaries formation,  where  we had  a progress and where we have  failed, what are new  breakthrough ideas.

Specific attention will be given to globular clusters, where dynamical interactions between  objects lead to the enhanced  formation of X-ray binaries. The only detected so far black hole binary with a white dwarf companion is located in a globular cluster, and its existence gives us the key what the unseen population of black holes in globular clusters could be.
