A good point but somewhat an overstatement. Socialist (not communist) elements were viewed as anti-oligarch and anti-monarchal but the anarchist ingredient was there as well. In response to this movement, in a big hurry, Marx and Engles wrote their flawed formula as to how socialism count be paid for — communism.
All in all the idea of re-examining many of the events around 1848 is a good idea. Here in the US our high school history ignores it.
I teach eight week college courses in music appreciation for non-majors, and I spend a whole week on how nationalism in music takes hold, beginning with Moniuzko and Chopin in Poland, and spreading throughout Europe. The students become interested in the variations in music based on the nationalist movements; practically none of them know about the revolutions of 1848 that begets a lot of this.
