The day of the regiment was on March 23, the anniversary of the decoration of its flag with the Virtuti Militari.The regiment was named after General Kazimierz Sosnkowski, who accepted the name on March 4, 1920. For 17 years it was unofficial, until November 21, 1937, when Ministry of Military Affairs officially accepted the full name: 7th Regiment of Lublin Uhlans of General Kazimierz Sosnkowski.
The regiment was formed in October 1918 in Lublin and Chełm, by a group of officers of Polish Legions 1st Uhlan Regiment, commanded by Wladyslaw Belina-Prazmowski (see Polish Legions in World War I). The officers decided to form three cavalry regiments in former Austrian part of Congress Poland.
The headquarters of the Lublin regiment was located in the barracks of Austrian uhlans in Lublin, its 1st and 2nd squadrons were located in Zamość, while 3rd squadron together with a machine gun squadron were garrisoned in Kraśnik.
On November 23, 1918, the regiment concentrated in Kraśnik, to be sent by rail to the Ukrainian front in eastern part of former Austrian Galicia. It fought the enemy in several locations, and on December 30, was renamed into 7th Lublin Uhlan Regiment.
On February 26, 1919, the regiment was transported northwards, to the area of Slonim and Lida, where it fought against the Red Army. In July 1919 it captured the rail junction of Molodeczno, to advance eastwards, and finally reach the line of the Berezina river. On November 23 the regiment was sent to the rear to rest and recuperate. It returned to the front on January 25, 1920, and patrolled the rail line from Riga to Daugavpils. In April it was incorporated into the 1st Cavalry Brigade, and on June 28 was resent southwards, this time to Volhynia.

In March some of its soldiers were sent home, in April the regiment was moved to Przasnysz, and in June, Polish military authorities decided that the regiment would be permanently garrisoned in Mińsk Mazowiecki – the uhlans arrived there on June 21. In the winter of 1922 – 23, elements of the regiment were sent to Eastern Galicia, to prevent the acts of sabotage, carried out there by Ukrainian nationalists.

In the final days of September 1939, elements of the regiment kept fighting both the Wehrmacht and the Red Army, trying to reach either the border with Hungary, or the garrison of besieged Warsaw. During one of the clashes against the Soviets, its commandant, Colonel Marian Skrzynecki, was mortally wounded. Last soldiers of the regiment continued fighting until October 9, when they capitulated near Mińsk Mazowiecki.
7th Regiment of Lublin Uhlans was recreated by the Home Army. Its units fought in Operation Tempest and Warsaw Uprising. Also, an armoured vehicle regiment of the 3rd Carpathian Rifle Division was named the Lublin Uhlans.
The flag of the regiment, funded by the residents of the Land of Lublin, was handed to it by General Sosnkowski in Kraśnik, on March 22, 1921. On the next day, in appreciation of the bravery of the soldiers, the flag was decorated by Józef Piłsudski with Silver Cross of the Virtuti Militari. On August 26, 1939, the flag was taken with the regiment to the frontline. It returned to Mińsk Mazowiecki on September 6. Saved by two soldiers, the flag was buried in the ground in the village of Nowodworze, where it remained until November 1959. It now is kept at the Polish Army Museum in Warsaw.
