BELGRADE, Serbia (August 29) -- Come the Olympic qualifying World Championships and the world of wrestling sees surprises like no other. The 2023 World Championships in Belgrade will throw more such results in September but what happened four years ago at the 2019 World Championships in Astana, Kazakhstan?

In front of a packed Bayrs Arena, champions went down to youngsters, dreams were shattered, wrestlers high on emotions. While some dreams remained unfulfilled, many wrestlers managed to live theirs.

Here's a throwback to 10 memories captured in these photos from the 2019 edition, a championship that saw Kazakhstan finish fourth in Freestyle team rankings, Japan winning only three gold in Women's Wrestling and Riza KAYAALP (TUR) winning a gold medal at the pre-Olympic World Championships.

It would have been a shame this was not the first photo from the 2019 World Championships. What happens when Haji ALIYEV (AZE), a three-time world champion and who has seen it all, suffers a loss after a thrilling bout in the opening round of a World Championships? Nothing good about that. Aliyev reacts towards the officials after his 4-2 loss to eventual champion Gadzhimurad RASHIDOV, before being escorted from the mat.

At the Tokyo Olympics, Aliyev would win a silver medal while Rashidov finished with a bronze after both were drawn on opposite side of the bracket.

J'den COX (USA) had beaten Alireza KARIMI (IRI) 5-2 in 2018. A year later, the two would meet in the final at 92kg. Cox would blank Karimi 4-0. Soon after the hand raise, Cox would let out a loud scream, holding the pose for the photographers. It was symbolic of Cox's dominance at the weight class as he became a two-time world champion.

Hometown hero: Askhat Dilmukhamedov (KAZ), red. (Photo: UWW / Tony Rotundo)

It was clearly Askhat Dilmukhamedov's world. The Bayrs Arena's loudest cheer over the nine days when the Kazakh Greco-Roman wrestler upset two-time Olympic champion Roman VLASOV in the 1/8 finals 3-0. He followed that up with a 4-3 win over returning world champion Viktor NEMES (SRB) to reach the semifinals. He would fall to the eventual world champion Tamas LORINCZ (HUN) in the semifinals, thus eliminating both Vlasov and Nemes. Incidentally, both Vlasov and Nemes failed to qualify for the Tokyo Olympics in later tournaments.

End of a drought: Mariya STADNIK (AZE). (Photo: UWW / Kadir Caliskan)

Mariya STADNIK (AZE) celebrates after pinning Yanan SUN (CHN) to reach the final at 50kg. 10 years after she won her first world title, Stadnik was a win away from her second. The then three-time Olympic medalist left Sun to fight for bronze, which she did not win. Stadnik's win did not just bring joy for her but for Yui SUSAKI (JPN) as well. Susaki got a second life, thanks to Stadnik. Susaki would go on to win the Olympic gold medal in Tokyo after beating Stadnik in semifinals and Sun in the final.

High Flying: Iszmail MUSZUKAJEV (HUN). (Photo: UWW / Tony Rotundo)

A photograph which aptly describes Iszmail MUSZUKAJEV (HUN). He is wrestling Cristian NICOLESCU (PLW) in his opening bout at 65kg. It seems Nicolescu has Muszukajev on the ropes with his attacks, forcing him to be airborne to defend. Come on! Wrestling fans knew Muszukajev but they got to really know him in 2019. Muszukajev would win the bout 14-4 not before letting Nicolescu score takedowns like he was chilling in a park. It was just the start of Muszukajev given jaw-dropping wrestling content.

The gold standard: Yong Mi PAK (PRK). (Photo: UWW / Kadir Caliskan)

Yong Mi PAK (PRK) looks at her coach while Mayu MUKAIDA (JPN) is in utter disbelief after Pak won the 53kg final via technical superiority. Pak became the first female world champion from DPR Korea. She won the best in Asia, winning two Asian Championships gold and the Asian Games gold in 2018. But to be a world champion made her the favorite for the gold in Tokyo. But soon a global pandemic would derail the world and DPR Korea would skip the Olympics in Tokyo. Mukaida went on to win the 53kg gold in Tokyo. Pak, perhaps, must have been similing if she watched the Olympics.

A win to remember: Sharif SHARIFOV (AZE). (Photo: UWW / Kadir Caliskan)

A 30-year-old Sharif SHARIFOV (AZE) takes out Olympic champion Kyle SNYDER (USA) after a battle. In one of the biggest upsets of the World Championships, Sharifov beat Snyder 5-2 in the 97kg semifinals and celebrated like a relieved man. The 2012 Olympic champion used his experience to shutdown Snyder. He would go on to lose the final against Abdulrashid SADULAEV but the semifinal win denied fans in Astana the third part of the Snyder-Sadulaev rivalry which ultimately happened in Tokyo.

Breaking Barriers: Aisuluu TYNYBEKOVA (KGZ). (Photo: UWW / Kadir Caliskan)

Aisuluu TYNYBEKOVA (KGZ) has broken many barriers related to Women's Wrestling in Kyrgyzstan. She was the first Olympian, first to reach a medal bout and in 2019, in front of a supportive crowd, Tynybekova became Kyrgyzstan's first-ever world champion in wrestling. Beating Taybe YUSEIN (BUL) in the dying seconds, Tynybekova completed a redemption of sorts as she suffered a heartbreaking loss in the bronze medal bout in Rio 2016. At the Tokyo Olympics, Tynybekova would lose the 62kg final to Yukako KAWAI (JPN), a wrestler the Kyrgyz star pinned in Astana.

Beginning of a Rivalry: Artur ALEKSANYAN (ARM). (Photo: UWW / Tony Rotundo)

Artur ALEKSANYAN (ARM) has rarely been challenged on a wrestling mat. The Rio Olympic champion and then three-time world champion Aleksanyan was tested in the quarterfinals. Mohammadhadi SARAVI (IRI) was unbeaten in international competition and was a U20 world champion in 2018. Aleksanyan was closer to legendary status in Greco-Roman. Yet, Saravi would put Aleksanyan on the brink and the latter would win only 4-3 against the 21-year-old Iranian. While Saravi is still looking for his first win over Aleksanyan, the two met in the semifinals of the Tokyo Olympics with Aleksanyan winning before finishing with a silver medal.

Continuing the Trend: Riza KAYAALP (TUR). (Photo: UWW / Tony Rotundo).

2011. 2015. 2019. The Greco-Roman world champion at 130kg in those three editions has been Riza KAYAALP (TUR). Yes, the pre-Olympic year World Championships gold belongs to the Turkish giant.
