We track the growth and accretion history of massive black holes starting from high redshift using two seeding models:(i) Population III remnants, and (ii) massive seeds from direct gas collapse. Although the seeds do not initially satisfy the $M_{\\rm BH} - \\sigma$ relation, the correlation is established and maintained at all times if self-regulating accretion episodes are associated with major mergers.
