Is there a clear reason for invitation ?
Chechen tried very hard to establish the first Islamic republic there :
In 1999, an Islamist group from Chechnya, led by Shamil Basayev and Ibn Al-Khattab, launched a military invasion of Dagestan, with the aim of creating an "independent Islamic State of Dagestan". The invaders were not supported by the local population and were driven back by the Russian military. As a retaliation, Russian forces subsequently reinvaded Chechnya later that year.
