The world championships in Hamburg will be the 19th edition of the tournament in men's boxing since the first in Havana, Cuba in 1974. The German cities of Munich and Berlin had hosted the event in 1982 and 1995, respectively.
Here's a look back at some of India's best memories from the past 18 editions, and a stat about the most successful nation in the sport's history at this level.
Pioneer of Indian men's boxing
Vijender Singh won 33 points in his four bouts leading up to his bronze, the first medal for India at the men's world championships, in the 75kg category in Milan, Italy in 2009. Vijender, who had won bronze in the same category a year before at the 2008 Beijing Olympics, was the top seed in the absence of the other medallists, but lost 3-7 in the semi-finals to eventual champion Abbos Atoev of Uzbekistan. He has since paved the way for Indian boxers to turn professional, winning his first nine consecutive bouts, including the most recent one against China's Zulpikar Maimaitiali.
Vikas comes good in Baku
Vikas Krishan had to negotiate a field of 63 boxers on his way to winning India's second world championship medal, a bronze in the 69kg category in Baku, Azerbaijan in 2011. Krishan, who was unseeded and thus had to start from the first round itself, beat boxers from Kyrgyzstan, Turkey and Moldova before losing 15-12 in the semi-finals to eventual champion Taras Shelestyuk of Ukraine. His biggest scalp was seventh-seed Mahamed Nurudzinau of Belarus, a former European champion as well as a world championship silver medallist from 2005. Krishan beat him in the second round in a split verdict after the bout ended with the scores tied at 10-10.
Knockout that set Thapa on his way
Among three Indian boxers to have won medals at the world championships, Shiva Thapa is the only one who has had a knockout victory on the way to his bronze in the 56kg category at the last tournament in Doha, Qatar in 2015. Thapa's fight against Mohamed Hamout of Morocco had to be stopped inside 26 seconds of the third round. He would win bronze after losing 3-0 in the semi-final to Murodjon Akhmadaliev of Uzbekistan.
Hoping for an encore
There are two returning medallists from India at the 2017 world championships: Krishan and Thapa. They will be joined by Manoj Kumar, Sumit Sangwan, Kavinder Singh, Amit Phangal, Satish Kumar and Gaurav Bidhuri, with India fielding eight boxers for the first time in the history of the event. The contingent for the last edition in Doha comprised six boxers, with Thapa the lone medallist from that group.
Established stars
Sixty-six competing countries have won medals at the men's world championships, with 32 of them winning at least one gold. Cuba has won the most gold medals (71). They have also won 32 silvers and 25 bronzes. Their tally of 128 medals is more than twice that of their nearest rival, Russia, who have 63 medals. Twenty-three of Russia's medals have been gold, though they also won an additional 15 goals as erstwhile Soviet Union.
