How to initialize multiple routers?

I have two resources in Routers: Students and Colleges.

class App.Routers.Colleges extends Backbone.Router
  routes:
   "index": 'index'
class App.Routers.Students extends Backbone.Router
  routes:
   'index': 'index'
   'new': 'newStudent'

How to initialise these two routes such that they work?

I have tried to initialize like the code below but it's not working.

window.App =
 Models: {}
 Collections: {}
 Views: {}
 Routers: {}
 initialize: ->
   new App.Routers.Students
   new App.Routers.Colleges
   Backbone.history.start()
 $(document).ready ->
   App.initialize()

When I try to run the above code, it's only showing me the data in new App.Routers.Colleges in both colleges and students div.

Routes in routers are added to the global Backbone.history object. So any identical route overrides the precedent ones. Even non-identical routes may override a similar but more specific route if defined after.

When instantiating a new Router, its constructor calls _bindRoutes which parses routes from the last to the first so specific routes should be defined first and the more generic routes after, ending with any catch-all route.

Every URL needs to be unique, so you could namespace every router with a prefix:

class App.Routers.Colleges extends Backbone.Router
  routes:
   'colleges': 'index'
class App.Routers.Students extends Backbone.Router
  routes:
   'students/new': 'newStudent'
   'students': 'index'

Or you could use (or make your own) sub-router/controller.
