All history is contemporary history meaning

Conceptual history is a branch of historical and cultural studies that deals with the historical semantics of terms.
It sees the etymology and the change in meaning of terms as forming a crucial basis for contemporary cultural, conceptual and linguistic understanding.
Conceptual history deals with the evolution of paradigmatic ideas and value systems over time, such as liberty or reform.
It argues that social history – indeed all historical reflection – must begin with an understanding of historically contingent cultural values and practices in their particular contexts over time, not merely as unchanging ideologies or processes.
