Editing Ivan I of Moscow (section)

===Relations with other princes===
No copies of the treaties with local princes have survived; as a result, there is largely only indirect evidence available to determine the relationship between Ivan and princes of the "Lower lands", a term found in the chronicles which refers to the principalities within Vladimir-Suzdal that had been distributed among the descendants of [[Vsevolod III]] from the 13th century onward.{{sfn|Fennell|2023|pages=176–177}} These include several key events: military campaigns by "all the princes of Suzdal" under Ivan's command, his right to purchase land, and the management of princely patrimonies and dynastic marriages under Muscovite administration.{{sfn|Fennell|2023|page=177}} According to later genealogical records, the principality of Rostov, which was originally the largest of the territories distributed by Vsevolod III, was split in 1328 between Fyodor and Konstantin, the sons of Vasily Konstantinovich, after Konstantin married Ivan's daughter Maria.{{sfn|Fennell|2023|page=177}} There are no records of any disobedience from Konstantin to his father-in-law and he became the sole ruler after Fyodor died in 1331.{{sfn|Fennell|2023|page=177}} [[Epiphanius the Wise]], the biographer of [[Sergius of Radonezh]], also portrays Rostov as something akin to a province of Moscow.{{sfn|Fennell|2023|page=178}}

Other princes, including those of [[Yuryev-Polsky (town)|Yuryev-Polsky]], [[Starodub-on-the-Klyazma|Starodub]], [[Galich, Russia|Galich]] and [[Dmitrov]], ruled quietly and in peace with Ivan and the khan.{{sfn|Fennell|2023|page=178}} The only princes who displayed any signs of opposition to Ivan were Vasily Davidovich of Yaroslavl and Roman Mikhailovich of Beloozero, both princes of districts that had separated from Rostov, who may have been partisans of Alexander of Tver, as the chronicle of Novgorod mentions that both princes were summoned at the same time as Alexander in 1339.{{sfn|Fennell|2023|pages=179–180}} Ivan concluded dynastic marriages with the two houses, and there is little evidence to suggest that those princes were able or willing to provide any more resistance.{{sfn|Fennell|2023|page=181}}

The [[Principality of Ryazan|Ryazan]] principality was under the influence of Moscow during the first decade of the 14th century; however, almost nothing is known about relations with Ryazan during the next 30 years, except that some kind of compact existed with the princes of Ryazan.{{sfn|Fennell|2023|page=175}} Ryazan's status was not lowered to semi-dependent as the prince of Ryazan still collected the ''vykhod'' (tribute) and brought this to the khan, not to the grand prince.{{sfn|Fennell|2023|page=176}} According to Presnyakov, during the reign of Ivan Korotopol as the prince of Ryazan, there was "significant and increasing independence of the principality of Ryazan in relation to the Great-Russian grand-princely centre".{{sfn|Fennell|2023|page=176}}
