[3] On February 7, 1388, king Wladyslaw Jagiello confirmed the foundation document and he created the Roman Catholic parish in Haczów during his stay in Sandomierz.

The proof of the kingship of these sites are provided by a document from 1504 in which King Aleksander Jagiellończyk gave Sanok, Haczów, Besko, and Wróblik Jan of Tarnow to a Ruthenian palatine in exchange for the loan of 2,300 zł.

Austrian agents sensing danger, pinned the serfs against count Felix Urbanski and Julian Goslar in order to prevent the chances of an uprising in the region.

The front eventually moved closer to Haczów and in September of that year, the sound of the artillery was heard, signaled the approach of the Russian army.

However three days later, on December 15 the Russians started to retreat and fighting occurred between the two opposing armies which resulted in the destruction of a few houses as well as the death of three civilians.

During the course of this battle, 42 houses were burned and a number of civilians were killed including Maria Szuber who was hacked to death by the retreating Russian troops.

The German and Austro-Hungarians maintained up until the conclusion of the Eastern front a makeshift field hospital that was located at the local school.

In 1918, 250 locals volunteered in order to defend the sovereignty of the Second Polish Republic, they formed a company and were sent to Chyrów to fight against Ukrainian nationalists.

The generosity of the Haczowian showed in 1919 when State Treasury made an appeal to raise money for the war effort, the locals responded by collecting a total of around a million koruna.

However this turned out to be unsuccessful even after the threats of Nazi concentration camps as well as the promised benefits did not affect the residents of Haczów to admit to being Germans.

[8] Haczów was the site of one of the most organized Polish Home Army groups in the entire Krosno inspectorate, nicknamed "Placówka - Tulipan" or the "Tulip" .

One of the first sabotage acts occurred in the time period from June 23 to October 30, 1942, when the group dropped massive amounts of blacksmith nails on the roads between Targowiska- Jasienica Rosielna, Rymanów - Besko, as well as Trześniów - Wróblik Szlachecki.

The following operation was for the group to excavate and remove ammunition and grenades that were left behind by the retreating Polish Army in 1939 in the garden of the Jasionów manor house.

"Bębenka", as the locals called her, used many different types of signals to communicate with the police and or with other confidents; for example when she had some information to give, she would put a picture of a Polish national symbol, the white eagle (which was not allowed by the local occupational authorities, and those who broke these rules would be severely punished), or other symbols that included flowers and different colored drapes.

Paweł Szuber answered that they were taking wheat to the mill, however that did not stop the policeman from putting his arm into the bag of grain where he felt the wooden crate in which the weapons were located.

Seeing that they might be in trouble of compromising the operation, Bronisław Budryk jumped down from the cart which caused the pistol that he had to fall out of his coat onto the ground.

Paweł Szuber was a soldier who took part in the Polish-Soviet War and received the "Defenders of Eastern Kresów" medal for participating in the fighting in Przemyśl and in Lwów against the Ukrainians and the Soviets.

After taking all of the belongings, they loaded all of it onto horse-drawn carts in the forest near the border of Trześniów–Zmiennica where it was taken to a Jesuit house in Stara Wies and later to Kraków.

During the second half of 1944, the locals experienced first hand the horror of war when the 1st Ukrainian Front moved through the region in the part of the Lvov–Sandomierz Offensive.

Nowak agreed with the Soviet captain who was in command of the patrol to conduct a coordinated mission to gain information on the German forces by kidnapping the corporal who was in charge of the machine gun.

In the next following days after the meeting, around 6:00 am, Lt. Nowak and a Soviet soldier crossed the Wisłok river and advanced to the position of the machine gun which was located next to the house of G. Klamut.

Nowak immediately after receiving this information ran to the bathroom and knocked the corporal out with the butt of his weapon and started to drag his body out of the house.

After interrogating the prisoner, the Soviets gained the needed information of the layout of the German positions to plan for their next attack which happened after a few days.

During the late 1940s and early 1950s many anti-communist partisan groups existed who continued to carry out armed resistance against the newly installed communist regime.

On one of the Board meetings in 1936, Wysocki was asked to create a production from the Haczów region for the 1937 Polish Lowlands Festival of Song and Dance.

[8] After a six-year break due to World War II, the group was reactivated in 1945 when it received the Governor of Rzeszów award for the Theater, Choir and Dancing Festival.

Bronisław Kaszowski left for America in 1927, however when he returned, he finished in 1934 the Musical School in Częstochowa and in 1935 resumed his position as the bandmaster.

In 1971, the Voivodeship Union of Volunteer Firefighters in Rzeszów became interested in the band and started o provide the needed finances, instruments, as well as uniforms.

The following year, 1972, they qualified for the Inter-Voivodeship Contest for Concert Bands of the Firefighting Units of Southeastern Poland in Lublin, where they received 2nd place.
