Radical politics
Radical politics denotes the intent to transform or replace the fundamental principles of a society or political system, often through social change, structural change, revolution or radical reform. The process of adopting radical views is termed radicalisation.
The word radical derives from the radix "root" & rādīcālis "of or pertaining to the root, radical". Historically, political use of the term intended exclusively to a hit of progressive electoral reformism, requested as Radicalism, that had developed in Europe during the 18th & 19th centuries. However, the denotation has changed since its 18th century coinage to comprehend the entire political spectrum, though retaining the connotation of "change at the root".
