This is a huge & complex answer - but in the short term I suggest you look at the life & work of Isadora Duncan who is often quoted as being the mother of contemporary dance. Then you should consider the work of Ruth St Denis, Ted Shawn & Doris Humphrey. After that move on to Martha Graham & later Merce Cunningham & Jose Limon. If you want the development of contemporary dance in the UK you need to look at the impact of Robin Howard (link to Martha Graham) & the London Contemporary Dance Theatre (& Dance School). This includes the work of people like Robert North, Siobhan Davies, Richard Alston, Chris Bruce, and onto some the the current younger British choreographers.
