Emperor Wilhelm II. In 1902–1903, gas pipes were laid in the village, and in 1935 electricity was introduced. The gasworks was close to the junction of ul. Poznańska and ul. Wojska Polskiego (formerly ul. Półwiejska). Near to this was the imperial post office building (still standing). In 1907 the soldiers of the German imperial army appeared in the village and on the market square while carrying out manoeuvres in the Poznań area. The village's development was slowed by the First World War and the Greater Poland Uprising of 1918–1919, in which many inhabitants were involved. Rebuilding of the village in the post-war independent Poland was slow. Among organizations founded were the Concordia sports club in 1921, and a church choir in 1926. The village's population grew from 1,595 in 1921 to 2,482 in 1931 and 2,800 in 1933 (2,417 Poles, 337 Germans, 16 Jews). Many of the German population (including Jews) emigrated to Germany in the interwar years. Germans accounted for 14% of the population of the village in the 1930s, and the number of Jewish families had fallen from 18 to two by 1939. In September 1939, following the German invasion of Poland, a resistance squadron of 40 armed volunteers forced a German patrol to retreat and fired on German engineers repairing a bridge over the Warta. In the first months of the war, 14 citizens of Murowana Goślina were executed, and 85 were taken to concentration camps, of whom 54 did not return. Also 45 soldiers were killed in fighting, four people died in the Katyń massacre, and many families were displaced. Since the Second World War The village was liberated on 21 January 1945, and on 23 January a civic militia (Milicja Obywatelska) was formed. The retreating Germans burnt down the railway station, the interwar post office at the junction of ul. Rogozińska and ul. Młyńska, and the occupiers' administrative building (Amtskomissariat) on the north side of the market square. Also destroyed by the occupiers during the war were the wall around the church, the church bell-tower, and the figures of the Madonna and Child, St. John Nepomucen and St. Laurence. For the next 44 years the village would be part of the communist Polish People's Republic. Its population in 1945 was 2,482 (compared with 2,700 in 1939); this increased to 4,399 by 1975, and this figure would more than double in subsequent years, particularly due to
