Islam is the last divine religion which Allah (glory be to Him) revealed to Muhammad (peace be upon him). Muhammad (peace be upon him) started calling all people, regardless of their color, race or tribe, to Islam. The Prophet (peace be upon him) made an enormous effort to reach those outside Quraysh through moving to them, sending callers to Islam or by messaging them.
