Step-by-step explanation:
In mid-June 1848, radicals were deeply involved in the revolutionary waves that swept across Europe, a period often referred to as the Year of Revolutions. Influenced by Enlightenment ideals, radicals pushed for greater equality and more rights for everyday people, echoing socialist ideas and seeking extensive social and political reforms. The tensions culminated in various events across Europe, including the publication of The Communist Manifesto by Karl Marx and Frederick Engels, which became a significant influence within these movements. In general, radicals aimed to overthrow the existing social and political orders and implement systems that they believed would lead to fairer, more egalitarian societies.
