Particle physics is entering an exciting time. In the coming years accelerator experiments together with particle and astroparticle physics observations can shed light on many key questions in particle physics and cosmology which are unanswered today. Together with the LHC the ILC will play a crucial role in this respect. This contribution deals with the ILC project comprising physics case, detector studies and accelerator development.
