This multi‑dimensional WWI‑WWII cause‑effect‑process research concept map template is a structured logical visual material developed for world‑history teaching, war‑history research and humanistic social‑science education. Centered on the annular core theme “World war”, it extends six core analysis dimensions including Causes, New Technology, Effects, Alliances, Brainstorming and The 10 most deadliest battles, with reserved multi‑level sub‑knowledge expansion nodes for each dimension. Adopting radial dark‑blue‑light‑green circular nodes and simple connecting lines, it features distinct layers and complete logic, fully covering the whole‑chain research framework of world wars from outbreak inducements and technological changes to camp confrontations, key battles and far‑reaching post‑war impacts. It can be directly applied to history‑class teaching courseware, war‑history academic research sorting, humanistic‑social‑science course display and student history‑project assignments. It is widely applicable to world‑history teaching materials for junior and senior high schools, university war‑history and international‑relations project analysis, research‑note frameworks for history enthusiasts, visual display materials for humanistic social‑science courses, history‑competition preparation materials, war‑history popular‑science content production and teaching aids for international‑relations subjects. Built according to the classic logic of historical‑event research, the template balances four major sections including background causes, process details, technological changes and post‑war impacts.
