Set active vertex through python

I am having a problem trying to set the active vertex in blender. I have a list of vertices but I cannot set the active vertex. I am able to retrieve the active vertex through select_history of the bmesh, but I cannot set it, says its not writable

#get bmesh
bm=bmesh.from_edit_mesh(bpy.context.active_object.data)

#print active vert
print(bm.select_history.active)

#if I do something like this, error not writable
bm.select_history.active = bm.verts[5]


You can add elements to the bmesh history. The last added element is automatically set as active element. Here is a small code example:

import bpy
import bmesh

me = bpy.context.edit_object.data

#get bmesh (Object needs to be in Edit mode)
bm=bmesh.from_edit_mesh(me)
