Frise du moyen age sur les phases de la Première Guerre

Historical timeline infographic titled "World War I Phases" — dominant HORIZONTAL timeline ribbon spanning 1914–1919, designed as a museum exhibition panel with decorative medieval-inspired border motifs and manuscript-style framing only, while keeping the historical content strictly accurate to World War I. Overlay the macro structure "Rise → Peak → Decline → Fall" across the ribbon, with each phase clearly segmented. Show 5 key milestone events, each with precise date or year, a short heading IN English, a one-line caption IN English, and a clear visual cue: 1) "28 June 1914" — "Assassination at Sarajevo" — "The killing of Archduke Franz Ferdinand triggered the July Crisis." — visual cue: crown and pistol with diplomatic scroll. 2) "28 July 1914" — "War Begins" — "Austria-Hungary declared war on Serbia, setting the alliance system in motion." — visual cue: sword, sealed treaty scroll, mobilization rail map. 3) "1916" — "War of Attrition" — "Battles such as Verdun and the Somme revealed the grinding stalemate of trench warfare." — visual cue: steel helmet, trench line diagram, artillery wheel. 4) "6 April 1917" — "United States Enters" — "American entry added major industrial and military weight to the Allied side." — visual cue: troop transport ship and factory gear. 5) "11 November 1918" — "Armistice Signed" — "Fighting ceased on the Western Front, ending the main combat of the war." — visual cue: broken sword, laurel branch, signed document. Include a small territorial/map element labeled "Europe at Peak Mobilization, 1916" showing simplified theaters: "Western Front", "Eastern Front", "Italian Front", "Middle East", with a subtle inset labeled "Global Theaters" indicating overseas colonial and maritime reach relevant to the conflict. Add 3 key figures in small portrait medallions with dates and exact labels: "Archduke Franz Ferdinand (1863–1914)", "David Lloyd George (1863–1945)", "Woodrow Wilson (1856–1924)". Visual style: editorial historical illustration, textbook-grade clarity, period-appropriate imagery, vector-clean lines, sharp readable typography, balanced infographic hierarchy, neutral scholarly tone, no propaganda framing. Color palette: ancient bronze & navy with parchment accents, muted steel gray, and restrained sepia highlights. Mood: dignified, analytical, curated like a museum exhibition panel. Avoid graphic battlefield gore, no real death photos, no flags or symbols of hate movements, tasteful and historically neutral presentation. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render dates in Arabic numerals. Avoid graphic battlefield gore, no real death photos, no flags or symbols of hate movements. For contested historical narratives, present neutrally — no propaganda framing, no glorification of atrocities. Period-appropriate but tasteful.
