Azerbaijan opens the 44-day Karabakh war
On 27 September 2020 Azerbaijan launched the offensive that became the 44-day war. In the causal graph this event strengthens Nagorno-Karabakh war (2020–2023+), a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — a worsening welfare path.

Read the full account
On 27 September 2020 Azerbaijan launched the offensive that became the 44-day war. Aliyev was president and commander-in-chief. Death totals are not invented here.
Context
The MoD issued communiqués. Turkey shared sensors and doctrine as a neighbouring file.
Start 27 September; trilateral 10 November 2020. Two 2020 Facts on one driver.
The president of Azerbaijan is head of state and commander-in-chief. He can decree, appoint a vice-president, and order force. He does not sit as a Baku trial judge, does not write ICJ orders, and does not write European Commission memoranda.
Why it matters
The path is nagorno-karabakh-war: a completed war-start. Not Ukraine. Not territorial-revisionism.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
Ilham Aliyev
PersonDirect responsibility
verified
He commanded. The MoD executed. He did not write a Russian peacekeeper order.

The UN in Armenia documented its response to people displaced by the 2020 conflict. Weight basis: Active interstate and territorial fighting drove substantial civilian displacement, but the scale was lower than the near-total 2023 exodus. Weight 0.83 is the pack's qualitative severity class for this event, not an empirical coefficient.

What the sources establish
Azerbaijani MoD carries the official instrument or communique. Reuters records the same dated act independently.
Established: Large-scale hostilities began on 27 September 2020 with Aliyev as commander-in-chief.
Not established: A unique agreed 2020 death total from the hour of the first strike.
The MoD executed. He did not write a Russian peacekeeper order.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Azerbaijan opens the 44-day Karabakh war, not a later speech about Azerbaijan opens the 44-day Karabakh war.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He commanded. The MoD executed. That limit is the alternative to treating office-holding as authorship of every later series.
The 2020 war over Nagorno-Karabakh began on 27 September and caused new civilian displacement on both sides of the conflict. The fighting itself drove civilians from homes and settlements, even though the 2020 displacement did not have the near-total population flight seen after the September 2023 offensive.
