 June 21, 1999: The Shimura-Taniyama conjecture  is proved.
 This conjecture says that every elliptic curve is modular. 
      The proof was achieved in four steps:
      First step: In 1995, Andrew Wiles proved, with a contribution from 
      Richard Taylor, that a large class of elliptic curves, including all semistable 
      elliptic curves, are modular. This was what was needed to deduce Fermat's
      Last Theorem from Ribet's Theorem (See 1995 on this page). 
      This first step was published in the following two publications:
      Andrew Wiles, Modular elliptic curves and Fermat's last theorem,  Ann. 
      of Math.
(2) 141 (1995), no. 3, 443--551. Review by Karl Rubin
  Link .
      Richard Taylor and AndrewWiles, Ring-theoretic properties of certain 
      Hecke algebras, Ann. of Math. (2) 141 (1995), no. 3, 553--572.
      Review by Karl Rubin
  Link .
      Second step: In 1996, Fred Diamond extended the first step to the proof 
      that every elliptic curve over Q with semi-stable reduction at 3 and 5 is 
      modular. This second step was published in the following publication:
      Fred Diamond, On deformation rings and Hecke rings, Ann. of Math.
      (2) 144 (1996), no. 1, 137--166. Review by Richard Taylor:  Link .
      Third step: In 1999, Brian Conrad, Fred Diamond, and Richard Taylor 
      extended the second step to the proof hat every elliptic curve whose 
      conductor is not divisible by 27 is modular. 
      This third step was published in the following publication:
      Brian Conrad, Fred Diamond, and Richard Taylor, Modularity of certain 
      potentially Barsotti-Tate Galois representations, J. Amer. Math. Soc. 
      12 (1999), no. 2, 521--567. Review by Ian Kiming  Link .
      Fourth and final step: In 2001, Christophe Breuil, Brian Conrad, Fred 
      Diamond, and Richard Taylor extended the third step to the proof that all 
      elliptic curves are modular. 
      The final step was published in the following e-publication: 
      Christophe Breuil, Brian Conrad, Fred Diamond, Richard Taylor, On the 
      modularity of elliptic curves over Q: wild 3-adic exercises, J. Amer. Math. 
      Soc.
14 (2001), no. 4, 843--939 (electronic). Review by Karl Rubin  Link .
