Why was Schrodinger's equation for the relativistic wave unsuccessful?

TL;DR

why was the schrodinger equation for the relativistic wave unsuccessful?

why was the Schrödinger equation for the relativistic wave unsuccessful?

The Dirac equation is the relativistic version of the Schrödinger equation for spin 1/2 particles and spin 1/2 fields. See for instance wiki, https://en.wikipedia.org/w/index.php?title=Dirac_equation&oldid=1003111291#Making_the_Schrödinger_equation_relativistic. The Klein Gordon equation is a relativistic equation for scalar fields (no spin) - see the same wiki.
