▼ills  at  the  same  time  divided  the  Roman  territory  into  fifteen
parts  (some  say  sixteen,  and  some  seventeen),  which  were  called
country  tribes.^

In  the  year  of  the  city  258,  the  number  of  tribes  was  made
twenty-one,  Li  v.  ii.  21.  Here,  for  the  first  time,  Livy  directly
takes  notice  of  the  number  of  tribes,  although  he  alludes  to  the
original  institution  of  three  tribes,  x  6.  Dionysius  says,  that
Servius  instituted  thirty-one  tribes.  But  in  the  trial  of  Ccmo-
lanus,  he  only  mentions  twenty-one  as  having  voted.^

The  number  of  tribes  was  tifterwards  increased  on  account  of
the  addition  of  new  citizens  at  different  times,  to  thirty-five,
'  which  number  continued  to  the  end  of  the  republic^

After  the  admission  of  the  Italian  states  to  the  freedom  of  the
city,  eight  or  ten  new  tribes  are  said  to  have  been  added,  but
this  was  of  short  continuance ;  for  they  were  all  soon  distributed
among  the  thirty-five  old  tribes.
For  a  considerable  time,  according  to  the  institution  of  Ser-
vius  Tullius,  a  tribe  was  nothing  el^  but  the  inhabitants  of  a
certain  region  or  quarter  in  the  city  or  country :  but  afterwards
this  was  altered ;  and  tribes  came  to  be  reckoned  parts  not  of
the  city  or  country,  but  of  the  stale.^  Then  every  one  leaving
the  city  tribes,  wished  to  be  ranked  among  the  rustic  tribes.
