In the Wallachian Revolution, Ion Heliade Rădulescu and Christian Tell proclaimed a new republican government in present-day Romania.

The Wallachian Revolution of 1848 was a Romanian liberal and nationalist uprising in the Principality of Wallachia. Part of the Revolutions of 1848, and closely connected with the unsuccessful revolt in the Principality of Moldavia, it sought to overturn the administration imposed by Imperial Russian authorities under the Regulamentul Organic regime, and, through many of its leaders, demanded the abolition of boyar privilege. Led by a group of young intellectuals and officers in the Wallachian Militia, the movement succeeded in toppling the ruling Prince Gheorghe Bibescu, whom it replaced with a provisional government and a regency, and in passing a series of major progressive reforms, announced in the Proclamation of Islaz.

Ion Heliade Rădulescu or Ion Heliade was a Wallachian, later Romanian academic, Romantic and Classicist poet, essayist, memoirist, short story writer, newspaper editor and politician. A prolific translator of foreign literature into Romanian, he was also the author of books on linguistics and history. For much of his life, Heliade Rădulescu was a teacher at Saint Sava College in Bucharest, which he helped reopen. He was a founding member and first president of the Romanian Academy.

Christian Tell was a Transylvanian-born Wallachian and Romanian general and politician.

The Proclamation of Islaz was the program adopted on 9 June 1848 by Romanian revolutionaries during the Wallachian Revolution of 1848. It was written by Ion Heliade Rădulescu and publicly read at the small port town of Islaz in southern Wallachia. On 11 June, under pressure from the masses, Domnitor Gheorghe Bibescu was forced to accept the terms of the proclamation and recognise the provisional revolutionary government.
