Russian leaders are called Czars showing influence from what place?​

Development of term The word "czar" is of Slavic origin, etymologically originating from the name "Caesar", as with the word 'tsar,' a title of sovereignty, first created and used by the First Bulgarian Empire. The title was later adopted and used by the Serbian Empire and Tsardom of Russia.

Explanation:

Tsar (/zɑːr, sɑːr/ or /tsɑːr/), also spelled czar, tzar, or csar, is a title used to designate East and South Slavic monarchs or supreme rulers of Eastern Europe, originally the Bulgarian monarchs from 10th century onwards,[citation needed] much later a title for two rulers of the Serbian Empire,[citation needed] and from 1547 the supreme ruler of the Tsardom of Russia and the Russian Empire.[citation needed] In this last capacity it lends its name to a system of government, tsarist autocracy or tsarism. The term is derived from the Latin word caesar,[2] which was intended to mean "emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official (the Pope or the Ecumenical Patriarch)—but was usually considered by western Europeans to be equivalent to king, or to be somewhat in-between a royal and imperial rank

so what is your question?

the results of roman expansion produced social conflict and civil war. julius caesar gained power and became a dictator but was then assassinated. the reign of augustus began a long period of imperial rule and peace in the roman empire. rome faced the problems of how to maintain peace, law, and order.

hope this !
