Vojvodina (Serbian and Croatian: Vojvodina ; ; Pannonian Rusyn: Войводина; Vajdaság ; Slovak and Czech: Vojvodina; Voivodina), officially the Autonomous Province of Vojvodina (Аутономна Покрајина Војводина / Autonomna Pokrajina Vojvodina; see Names in other languages), is an autonomous province of Serbia, located in the northern part of the country, in the Pannonian Plain.
Novi Sad is the largest city and administrative center of Vojvodina and the second-largest city in Serbia. Vojvodina has a population of almost 2 million (nearly 27% of Serbia's population excluding Kosovo). There are some 26 ethnic groups in the province, and six languages are in official use by the provincial administration.
The term vojvodina in Serbian means a type of duchy – more specifically, a voivodeship. It derives from the word "vojvoda" (See: voivode) which stems from the Proto-Slavic language word "voevoda". Those words are etymologically connected with modern-day words "vojnik" (soldier) and "voditi" (to lead). Its original name (from 1848) was the "Serbian Voivodeship" (Српска Војводина/Srpska Vojvodina) which then became "Voivodeship of Serbia" (Војводство Србија/Vojvodstvo Srbija).
