  The artefact is dedicated towards the inspection of nonlinear fractional
differential systems involving Riemann-Liouville derivative with higher order
and fixed lower limit, including non-instantaneous impulses for existence and
uniqueness results in Banach spaces. The motive of the paper is to set
sufficient conditions to guarantee the existence of mild solution in Banach
spaces. Firstly, appropriate integral type initial conditions depending on the
impulsive functions are chosen at suitable points. A mild solution of the
concerned system is constructed using fractional resolvent. Subsequently,
existence and uniqueness results are established under sufficient assumptions
utilizing fixed point approach. An example is presented at the end to validate
the methodology proposed.
