 The new executive, orchestrating the public burning of the "Regulament" in September, attempted to play Ottoman interests against Russian ones, trying to obtain backing from the Porte; the relative initial success was rendered void after Russian diplomats pressured Sultan Abd-ul-Mejid I to intervene in their place (and thus not risk losing yet more control over the region to a more determined Russian expedition).A Russian occupation over Wallachia soon joined the Ottoman one (begun on September 18), and both lasted until April 1851; in 1849, the two powers signed the Convention of Balta Liman, which asserted the right of the Porte to nominate "hospodars" for seven-year terms.The Crimean War again brought the two countries under Russian military administration, inaugurated in 1853.
