Query: Future colliders - Linear and circular   The completion of the Standard Model of particle physics by the discovery of
a light Higgs boson at the LHC in 2012 triggered the debate about the best way
forward to discover physics beyond the Standard Model. At the eve of the update
of the European Strategy of particle physics, this article summarises the
motivation and status of the different collider projects in particle physics at
the energy frontier. This article reflects the status as of December 2018 and
the reader is invited to follow closely updated information of the presented
projects.
