## TL;DR
Django is a high-level Python web framework (2005) that follows 'batteries-included' philosophy. ORM, admin interface, authentication, form handling, and templating are built-in. Follows MVT (Model-View-Template) architecture. Used by Instagram, Pinterest, Mozilla, Disqus.
## Core Explanation
ORM: `User.objects.filter(active=True)` — Python code maps to SQL. Admin: auto-generated CRUD interface from model definitions. URL routing: `urlpatterns` with regex/path converters. Template language: Django Template Language (DTL) with inheritance, filters, tags. Middleware: process request/response globally (auth, CSRF, sessions). Django REST Framework (DRF) adds REST APIs with serializers and viewsets.
