[3] He has been locally approved for veneration in the Russian Orthodox Church, with feast days on March 17 and September 12.

Of his father's patrimonies, he received the least valuable, Moscow, and reigned under the regency by his paternal uncle, prince Yaroslav of Tver.

[citation needed] Daniil took part in his brothers'—Dmitri of Pereslavl (Pereslavl-Zalessky) and Andrey of Gorodets—struggle for the right to govern Vladimir-Suzdal and Nizhny Novgorod, respectively.

The Mongol warlords Nogai Khan and Tokhta grew in power in the late 1280s, and in 1291 they jointly conquered Sarai, capital of the Golden Horde.

[2] The main conflict in the following years would be over the question whether Andrey had the right to reign over Pereslavl-Zalessky as Grand Prince of Vladimir, or whether it was an appanage which was inherited from father (Dmitry) to son (Ivan Dmitrevich).

[2] In the assembly of 1296 (or congress of 1297[6]), the Rus' princes as well as Tokhta's representative Nevrui (or Ivrui[6]) and the bishop of Sarai deliberated on the issue.

[citation needed] In 1302 his childless nephew and ally, Ivan of Pereslavl, bequeathed to Daniil all his lands, including Pereslavl-Zalessky.

[9] This is why Khan Tokhta granted Mikhail of Tver the Vladimirian grand princely title when Andrey of Gorodets died the next year (27 July 1304).
