The first battles in Russia's latest Chechen war were fought in in the less well-known neighbouring republic of Dagestan.
More than 1,000 militant fighters declared the independence of an Islamic Dagestan and proclaimed a holy war against Russia in August 1999.
The fighters were members of the Muslim fundamentalist Wahhabi sect, and said they were seeking to install Sharia law in Dagestan.

They were led by the Chechen field commander
Shamil Basayev and the Arab warlord known as Khattab - both experienced guerrilla fighters, who have made it their mission in life to fight the Russians.
Dagestan is home to more than 30 ethnic groups. It is also mainly Muslim, with more in common with its North Caucasian neighbours than with Moscow.
The rebels took advantage of its high mountains and porous borders to pursue their aim of establishing an independent North Caucasus, with access to the Caspian Sea.
But although Wahhabism is strong in some areas, most Dagestanis are moderate Muslims.
Russian response
Vladimir Putin - then Russia's acting prime minister - vowed to quash the rebellion in Dagestan within two weeks.
But the rebels proved harder to defeat than Russia had anticipated, and the fighting dragged on for weeks.
Russia lost no time in claiming that Chechnya was the key to the problem.
Moscow decided to begin cross-border raids into Chechnya to destroy rebel bases.
"Chechnya is Russian territory and we will strike at militants wherever they are located," Mr Putin said.
In the early stages of the offensive, Mr Putin said Russia's aim was to destroy the bases of Islamist militants "from a distance" and use "special forces" only at a later stage.
But as the war in Chechnya gathered momentum, Russia's goals appeared to be widening: what began as a conflict against "terrorists" began to resemble a new attempt to crush Chechnya's self-declared independence.
Chechnya's elected President, Aslan Maskhadov, said his government had nothing to do with the incursion into Dagestan.
But in a shift of policy Mr Putin sidelined President Maskhadov, declaring that a long-forgotten parliament in exile had more legitimacy than the leader Moscow itself had recognised in 1997.
