in Kalingrad and they got divorced within a few months of his first invasion against Ukraine.
Also she had a role in opposing Russian language reform, and I have read other articles speculating as to why the letter Z is on Russian invasion vehicles as it's not in the Russian alphabet.
Early life and education
(snip)
Lyudmila was born in
Kaliningrad, Soviet Union, the daughter of Alexander (his patronym is reported variously as either Abramovich[2][3][4] or Avramovich) Shkrebnev (Александр Абрамович Шкребнев or Александр Аврамович Шкребнев and Yekaterina Tikhonovna Shkrebneva (Екатерина Тихоновна Шкребнева

. Her father worked at Kaliningrad Mechanical Plant.
She was educated as a linguist.[5] In 1986, Lyudmila graduated from the branch of Spanish language and philology of the Department of Philology of Leningrad State University.[6]

Role in spelling controversy
As First Lady, Lyudmila Putina was a curator of a fund that aimed to develop the Russian language and sometimes produced statements concerning Russian language and education. Her preference for "maintaining and preserving"[20] the Russian language led her to make public statements against orthographic reform. The Russian Academy of Science sponsored a commission to study the orthography of the Russian language and propose changes. Their recommendations were made public in 2002 after eight years of work, but were subsequently rejected by Putina, who used Russia's burgeoning economy as one of her reasons why the orthographic reform was not just unnecessary but untimely. However, although one newspaper in Moscow alleged that "Lyudmila Putin de facto cancelled any attempts to reform spelling," the fact remains that public and academic reaction to the reforms was sufficiently negative to have that particular reform attempt abandoned.[21]

On 6 June 2013, she and Putin publicly announced the termination of their marriage based on a mutual decision.[22] The divorce announcement was made on camera for the Russian news media at the State Kremlin Palace during the intermission of a performance by the Kremlin Ballet, ending years of speculation about their relationship.
In April 2014, the Kremlin confirmed that their divorce had been finalized.[23][24]

It makes me wonder if Putin's ex has any family in Ukraine or if she privately opposed the first invasion?
