The left half depicted a white eagle with yellow (golden) legs, with risen wings. The right half depicted a knight in a white (silver) armor, sitting on a white (silver) horse with a blue saddle and shabrack, standing on its back hoofs.

The voivodeship existed until 23 lutego 1837, when it was replaced by the Podlachian Governorate, which continued using said coat of arms. It ceased to exist in 1844, when it was incorporated into the Lublin Governorate.

Following the merge of the two governorates, the Lublin Governorate began using a new coat of arms design which combined the symbols of the former governorates. It was divided into four fields, two on top, and two on bottom. The top fields referred to the former coat of arms of the Lublin Governorate. The top left field depicted a white (silver) male jumping cervus (deer), with a yellow (golden) crown on its neck, placed on a red background. The top right field depicted a white (silver) bear and a tree trees growing on a green grass, placed on a green background. The bear stood behind the middle tree. The bottom fields referred to the former coat of arms of the Podlachian Governorate. The bottom left field depicted a white eagle with yellow (golden) legs, rising its wings, placed on a red background. The bottom right field depicted a knight in a white (silver) armor, sitting on a white (silver) horse with a blue saddle and shabrack, standing on its back hoofs. The knight has a blue shield with a yellow (golden) cross of Lorraine on it, put on his left arm, and hold a sword in his right hand. They are placed on a red background. The coat of arms was approved by the viceroy of Poland, Ivan Paskevich, on 5 October 1845, and later, by the tsar or Russia, Nicholas I, on 26 May 1849. It remained in use until 1866.

In 1867, from the portion of the Lublin Governorate had been formed the Siedlce Governorate, within the borders of the former Podlachian Governorate. Its coat of arms had been approved on 25 February 1869. The coat of arms depicted a red deer with yellow (golden) antlers, hoofs, eyes and a tongue. It was placed on a white French-style escutcheon with a pattern of green oak leaves scattered on a shield. Around the shield, there were yellow (golden) leaves of the oak tree, interspersed with the blue ribbon of the Order of St. Andrew. On the top of the coat of arms, above the escutcheon, there was the yellow (golden) Imperial Crown of Russia. The coat of arms was used until 1912, when the governorate ceased to exist.
