Abstract
The problems faced by Einstein in formulating the general theory of relativity are discussed. Einstein derived the generally-covariant version of identities, which in conjunction with the field equations imply energy-momentum conservation. Einstein also showed that the identities guaranteeing energy-momentum conservation are a direct consequence of the covariance of the action functional. He also derived the generally-covariant field equations from an action principle with the Riemann curvature scalar as the Lagrangian.
