The "June Days" refers to a series of events that took place in France in June 1848. These events were marked by a workers' uprising in response to the government's decision to close the national workshops, which provided jobs for the unemployed. The protests escalated into violent clashes between the workers and the government forces. The uprising lasted from June 23 to June 26, 1848, resulting in significant casualties. The government eventually suppressed the revolt, leading to the establishment of a more conservative regime. The June Days highlighted the social tensions and class struggles in post-revolutionary France, influencing future political movements and reforms.
